Hi Guys,
Please be advised of the following maintenance window:
Maintenance Window: Saturday March 20th 2010, 7:00pm - 11:00pm 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 Priority Colo’s Automatic Transfer Switch (ATS), thus performing a full load generator test. Building management will open the circuit breakers at our mains, allowing our ATS 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.
For those who may notice this is effectively a repeat of the maintenance done this past Saturday March 13th, during which we experienced some anomalous readings that warranted further investigation. Given this, the building has agreed to perform a more in-depth test to investigate any potential issues, and ensure we're able to resolve them as quickly as possible.
Regards,

Re: 20-Mar-2010 - Generator Testing & Maintenance
This maintenance period can now be considered closed. We will be scheduling a new maintenance window for next weekend at the same time.
While we believe we have isolated (and resolved) our previous concerns, we will be running another barrage of tests next weekend, once both UPS-A and UPS-B's batteries have had a chance to fully recharge.
