Tor1 UPS Maintenance - 07-Nov-2025 - 9:15am - 4:00pm Eastern Time

[porcupine]

Hi Folks,

Please be advised of the following maintenance window:

Maintenance Window: Friday November 7th, 2025, 9:15am - 4:00pm Eastern Time
Affected Device: UPS-A.tor1, UPS-B.tor1
Affected Customers: Web Hosting/Reseller Hosting Customers, Dedicated Server Customers [in Tor1], Colocation Customers [in Tor1]
Service Impacting: No - Precautionary Notice Only

Details: Eaton Powerware will be performing standard preventative maintenance on both UPS units in preparation for the buildings planned "Diesel Day" maintenance, which will be announced shortly. While we do not expect this to be a service impacting maintenance, the UPS unit(s) will be operating on bypass mode, and should utility power fail at that 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.

We expect each UPS unit to be on bypass for less than 45 minutes during this maintenance window, allowing technicians sufficient time to perform any/all invasive tests & maintenance items that need to be performed. The bypass will be staggered, to ensure both units are not on bypass at the same time.

Regards,
