Please be advised of the following maintenance window:
Maintenance Window: Tuesday June 30th, 2020 7:15am - 3:00pm Eastern Time
Affected Device: UPS-A.tor2, UPS-B.tor2
Affected Customers: Tor2 colocation customers
Service Impacting: No - Precautionary Notice Only
Details: We will be replacing the UPS batteries powering UPS-A.tor2, and UPS-B.tor2 with new batteries. The batteries in both of these plants have been in service for over 6 years. While the current batteries are rated for a 10 year service life, recent tests have demonstrated increasing impedance levels, suggesting the current batteries are reaching the end of their useful service life, and should be replaced accordingly.
While we do not expect this to be a service impacting maintenance, the UPS units will be operating on battery bypass, and should utility power fail at this time, there will be an interruption in services as the Automatic Transfer Switch (ATS) switches power from utility to generator. As such, this should be considered a precautionary maintenance window. Batteries will be replaced on a shelf by shelf basis, and efforts will be made to minimize time on bypass as one would reasonably expect.
While both UPS plants will have their batteries replaced on this date, at no time will both UPS plants be in battery bypass mode. UPS-B.tor2 will be upgraded first, during which time UPS-A.tor2 will continue to operate in normal/protected mode. Once UPS-B.tor2's battery replacement has been completed, it will be returned to normal/protected mode, and we will work on UPS-A.tor2, ensuring that customers with A/B power are fully protected throughout the maintenance window.
