The Network Operations team will be modifying the BGP routing configuration of the transit routing network for all data centers. After modifications, testing will be done to verify optimized transit routing. Once modifications have been completed, transit link failure will be simulated to verify correct operation in an upstream failure scenario.

This maintenance operation is composed of three activities:

• Modification of BGP transit routing configuration
  The BGP configuration of each transit router will be modified to optimize traffic flow and increase network redundancy. Customers in each data center may experience brief (up to 60 seconds) of latency as BGP routing tables are recalculated.
• Testing and optimization of BGP transit routes
  Network Operations will test incoming and outgoing transit paths for best routing and performance. Minor modifications to BGP configuration may be introduced to optimize inbound and outbound routing. Customers will not be affected during testing phase, but may experience brief periods of latency (up to 60 seconds) if BGP modifications are made.
• Verification of system fault tolerance with upstream transit links
  Network Operations will simulate failure of each upstream transit link to verify traffic re-routing. After simulating upstream link failure, intra-data center links will be failed and connectivity testing will be performed. Customers in each data center may experience brief (up to 60 seconds) of latency as BGP routing tables are recalculated. During intra-data center link failure, customers may experience up to 120 seconds of connectivity interruption while testing is being performed.

Level3 did emergency maintenance (Tkt# 1798870) on the OC-192 SONET Link provides a portion of our IP transit. The circuit was generating critical errors and the fibers were literally removed and cleaned.

Since this event occurred in the middle of the Level3 network (and not adjacent to our network), the BGP routing session was not affected and the Level3 router was still advertising its routes to our routers. This meant that sites using routes from our other transit providers were operating normally, while many of those routing through the Level3 network were not accessible.

This effect was compounded by the fact that other networks also prefer Level3 to reach our network; their BGP routers were telling them that the Level3 network was intact.

The only way to force failover was to cut our connection to Level3, then re-route traffic over our remaining transit links.

This issue appears to be completed resolved and Level3 does not anticipate further maintenance being required on this circuit.

At 5:30pm this evening engineers will take 1 of the 2 primary UPS systems supporting the C5 datacenter offline for routine maintenance. This UPS system supports less than 100 customers in a portion of the C5 facility. Power redundancy will be provided by generators while this maintenance takes place.

At 11:15am, the UPS system protecting our C2 datacenter experienced a catastrophic system failure. During this failure, the system control board were damaged, which prevented the cutover to generator power. Power was down to the facility for less than 5 minutes as the UPS was bypassed and generator power was implemented.

Cali-Web.com network service personnel began a server by server inspection to ensure that all customer servers were back in operation. Hardware replacements and reboots were handled as top priorities, and customer phone calls and cases were answered in a first come, first serve basis.

All UPS systems which support Cali-Web.com datacenters are constantly maintained and serviced by industry experts. A replacement UPS is on order as a precaution, and a certified repair team will be onsite first thing tomorrow (11/16/06) to assist in bringing the UPS back online without further incident. Further information will be provided as it becomes available.

We apologize for any issues that this outage may have caused. We are working hard to ensure that issues of this nature do not resurface.

We are pleased to announce that on October 26th, 2006, construction began on the expansion and upgrade of the C3 datacenter (our Collocation facility). This expansion and upgrade will entail 2+ months of work as our existing raised floor, gas based fire suppression protected collocation facility is expanded to house more than 100 additional customer cabinets. In addition to the additional customer space - brand new, completely independent power infrastructure is being installed to support new and existing customer requirements.

A unique approach is being taken with this expansion and upgrade. Instead of simply increasing capacity to existing power infrastructure, a completely new UPS system, Generator, and electrical power grid are being installed to support the additional space. In doing so, the C3 facility will be one of only a hand full of datacenters throughout the U.S. capable of offering true, 100% power system redundancy to our customers. Existing C3 customers will be able to purchase power feeds from both the existing power grid, and from the new completely independent power system and source, and new customers will be able to elect the same reassuring levels of power redundancy.

Further updates will be made available when available and as required by our construction schedule. Should you have any questions or if you have inquiries about the expansion or additional power redundancy needs, please feel free to contact Chris Orlando, VP Sales & Marketing at 661-309-5684.

One of our transit providers will be performing a software upgrade on their directly attached peering router. This 15 minute process involves loading new software on the router and rebooting it. There will be two short periods of increased latency for some customers as routing adjusts to the loss and restoration of this transit link.

Cali-Web.com's Network Engineering team will be performing an emergency switch replacement at 1:10pm this afternoon. Our monitoring of this switch leads us to believe that equipment failure is eminent, so we are taking preventative measures to avoid additional and more costly outages.

At 1:10pm the offending switch will be replaced with a new piece of equipment. If you are receiving this case update, your server is connected via the affected switch. This you will experience loss of IP connectivity while the switch is replaced, our team will work as quickly as possible to restore service to your equipment.

At 18:15 this evening 1 of our primary upstream providers appeared to be experiencing routing issues within their network. The issue affected a small number of customers on our network, while others remained unaffected. We are working with our upstream to identify the issue. As of this moment, we have disconnected this provider until we can be guaranteed the problem will not resurface. More information will be provided on this page as soon as it is available.

On Friday, September 15 at 11:00pm, the Systems and Networking division will be installing an additional router in the C3 datacenter. This router is being installed to add redundancy for the collocation facility. In addition, core routing equipment in the C5 datacenter will be replaced with a new chassis and dual routing engines.

The Systems and Networking Division will be upgrading two core network routers on Friday, September 1st at 23:00 PDT. New redundant routing modules will be installed in core routers in the C3 and C5 data centers.

As part of our ongoing effort to ensure the highest level of service for our customers, we will be performing a series of tests on the iBizPanel. These tests will ensure that newly installed iBizPanel redundant systems are fully functional. We will begin these tests tomorrow (8/30/06) at 12:00am EST with a controlled failover to the new redundant systems. We expect no down time during this process. Being that a seamless cutover is the primary objective for this test we will be monitoring the system very closely. If problems do arise we will restore normal operations on the primary systems within minutes. After a complete 24 hour test of the secondary systems, we will return services to the primary systems the following evening (8/31/06) at 12:00am EST.

Thank you for your continued patronage.

Network capacity is being added between the C2, C3, and C5 datacenter facilities to increase inter-facility redundancy to our transit IP carriers. Additional Gigabit links will be installed by the Network Engineering Division on the evening of 8/18/2006 at 23:00 PDT (11:00pm).

***THIS WORK HAS BEEN COMPLETED AS OF 9:28pm ALL SERVICES ARE AT 100% ***

SDGE has reported a problem with 2 of the primary electrical transformers that feed power into the industrial business park where our datacenters are located. This problem is of a critical nature, and SDGE has insisted that these primary transformers be replaced immediately. SDGE will be onsite from 5pm until 12am this evening to perform these emergency replacements.

During this maintenance window, we will be running C3 (our carrier grade Collocation facility located at 8913 Complex Drive) on generator power to ensure continuous operations. Shared Hosting and Dedicated Server customers in C2, C3, and C4 are being notified as a precaution, since the transformers being replaced feed power to the entire business park.

While we do not expect any downtime whatsoever during this emergency maintenance window, our facilities will be fully staffed during this window, and senior level personnel will be onsite 100% of the time managing this event.

SDGE will be onsite at 5pm. They expect to start work at 5:30pm and expect to complete their work by 11:30pm. We will info you as soon as the work has been completed by updating the network-status page on our website, and by sending a follow up email message.

System Engineers will be making upgrades and modifications to our clustered Webmail server farms over the next week. These upgrades will include migrating individual machines to new 4-way DUAL ZEON servers for faster responses and more processing power. Webmail users will benefit from faster logins, quicker IMAP folder listings, and generally improved email service.

Bandwidth usage between all 5 datacenter facilities has increased tremendously over recent months.

Additional Gigabit links will be added to improve throughput between facilities and to our primary IP carriers located throughout the different facilities.

During the week of 8/1/06, a new 20 Ton AC unit will be added to the C2 facility for additional cooling. Existing air conditioning has been sufficient in the past, but due to the recent heat wave in Southern California, this additional unit is being added to guarantee that enough AC capacity is available to our clients, even on the hottest of days. This increase in AC capacity should be completed by 8/7/2006.

Update – this maintenance window was delayed from 07/25/06 to 07/26/06. Same time frame. —Due to the heat wave that has struck Southern California and much of our nation, Cali-Web.com will be undertaking some preventative maintenance to avoid any large scale outages associated with the heat wave. We will be making adjustments to our C2 datacenter to ensure proper cooling and power redundancy during the summer months. These changes will affect less than 80 customers. You will receive a case update if your services will be affected. The maintenance is scheduled to begin around 11am. Total affected time for each server should last no more than 15 minutes once the window has begun. Our teams will work as quickly as possible to restore service to the affected areas.

Our personnel will be migrating services and customer equipment from our C2 facility to the C4 facility for further redundancy. This migration will affect less than 75 customers. You will receive a case notification if you are among the affected customers. The maintenance is scheduled to begin at 11am today. Total affected time for each server should last no more than 30 minutes one the window has begun. Our teams will work as quickly as possible to restore service to the affected customers.

2006, June 23rd

Cali-Web.com will be restructuring and upgrading the three primary data center networks (C2, C3, and C5) to increase fault tolerance and overall network performance. This action includes redistribution of core support services such as DNS and business automation systems. Although our facilities currently have redundant UPS and emergency power generators in place, we are taking these additional measures to minimize the risk of a single power grid outage disrupting service across multiple data centers.

The restructuring project will require several non-standard maintenance windows since we will be adding and moving fiber optic links between our data centers and transit (backbone) carriers. Every effort will be made to minimize the impact of these actions on network services, but some customers may experience very brief intervals of interrupted or re-routed traffic as new links and network equipment are brought online. Whenever possible, we will perform these upgrades outside of standard working hours.

During the course of normal network operations there are small network reconfigurations, such as replacement of network equipment or the reconfiguration of core network equipment to optimize traffic flow. These changes are usually undetectable and transient in nature. Due to the larger scale of this infrastructure reconfiguration, there will be an increased chance that it could have a noticeable ?but transient ?impact on network services.

Here is a summary list of planned (and in some cases, completed) activities that will be completed for the network upgrade:

• Installation of core routing and switching capacity in C5 data center. (Completed)
• Installation of fiber capacity between C2 and C5 data centers. (Completed)
• Installation of additional fiber capacity between C2 and C3 data centers. (Completed)
• Upgrade of collocation network and switching equipment in C3 facility. (Completed)
• Relocation of transit carrier (Cogent) from our C1 data center to our C2 data center. This will occur at 11:00pm Monday, July 10th.
• Reconfiguration of C2 distribution switching network to support additional core router and network segmentation. (Ongoing, various times)
• Transfer of transit service (Level3) from our C1 data center to our newest data center (C5). This move will take place during our standard maintenance window on Wednesday, July 12th, at 11:59pm.
