Telehouse – UPS Replacement *At Risk* 20/01/2023 – 21/01/2023

We have been advised by Telehouse that they are undertaking power works to replace both UPS systems feeding the colocation suite where one of our racks is located as part of there Hardware upgrade program.

During these enabling works, Telehouse we will be isolating one UPS extension switchboard at a time covering two separate dates. This will ensure that there is one UPS System supporting our customer’s rack power load on each of these dates, to avoid total loss of power.

All of our hardware at this location is diversely fed by by dual redundant power supplies and we don’t expect any interruption to power or services but this should be classed as *At Risk*. Telehouse have provided a detailed scope of works that we have been asked not to share but they are very comprehensive and details power should not be disrupted for any great length of time.

Due to the unforeseen issues that arose last Friday. Structured engineers will be on site for the duration of the works being completed.

We have also decided to replace the the PSUs in our core devices prior to the works taking place and to manually transfer power away from the power feed being worked on to better manage any unforeseen outages this time.

Structured works will start at 19:30 to replace power supplies

Telehouse works will commence from 20:00
