Priority Colo Inc.

Hi Guys,

Please be advised of the following maintenance window:

Maintenance Window: Saturday March 13th 2010, 7:00pm - 11:59pm EST

Affected Device: Primary power feeds
Affected Customers: All customers
Service Impacting: No - Precautionary maintenance notice

Details: Building management will be performing a simulated main power failure, in order to test the generators, and customer side Automatic Transfer Switches (ATS's), thus performing a full load generator test. Building management will open the customer power circuits at the mains, allowing our ATS's to transfer load and start the generators, as would happen in a real power failure. During this maintenance, our Uninterruptable Power Supplies will carry all critical/server load, until the generators have started, and are ready to accept the load. Building management has pre-checked fuel levels in the day tanks, and reserve tanks, and will have numerous contractors on-site in case of incident. In the event of critical failure, commercial power will be immediately restored. Priority Colo staff will also be on-site for the duration of this maintenance as a precautionary measure.

Regards,

Hi Guys,

This maintenance period is now closed. While customer services/critical load was not interrupted, this maintenance period did not go a smoothly as hoped, and we will be rescheduling another, more in-depth series of tests for Saturday March 20th, 2010, from 7:00pm to 11:00pm EST (notice will be sent out shortly).
