Priority Colo Inc.

Hello Everyone,

Please be advised of the following maintenance window:

Maintenance Window: Monday December 7th 2009, 11:30pm - 5:30am EST

Affected Device: UPS-A Dedicated Server branch circuits
Affected Customers: Dedicated Servers, with Resource Numbers beginning between D-A1, and D-A9
Service Impacting: No - This is a precautionary maintenance window. We do not expect to see any loss of power, or other interruptions to customer services during this maintenance window in question.
Details: We will be migrating approximately 50% of the named APC Masterswitches powering the Dedicated Servers from our UPS-A power plant, to our newly installed UPS-B power plant, in an effort to improve efficiency, reduce UPS-A's load, and extend customer distribution, run-time, and redundancy in general. We have developed a proprietary set of tools and techniques, which have been previously tried, tested, and which allow for Priority Colo's staff to migrate power distribution units between branch circuits in a safe and consistent manner, without interrupting any of the connected equipment. Upon completion of this maintenance period, we expect the APC Masterswitch units, and thus their load to be evenly spread across the two UPS's, giving customers with multiple servers, some additional diversity.

This precautionary notice is being sent out, due to the nature of the maintenance in question.


Regards,

Just an update for everyone, the dedicated server power migration has been completed successfully. We migrated approximately 11kw of power from our UPS-1 plant to our UPS-2 plant, without a single incident.

This precautionary maintenance period is thus closed.
