Update from Volta/Verne:

We have planned works to install temporary power supplies to replace the faulty equipment identified in the LV switch panels. We will commence a simulation of the procedure at 6pm GMT and will send an update out once complete to outline the schedule of proposed works.

The simulation will not affect customer supply.

Update from Volta/Verne:

Data Centre remains stable with all 3 UPS systems online.

We are currently working on a fix that can be put in place until such time as the replacements for the faulty equipment can be received and installed. Fix is expected to be started after 5pm GMT today and will be implemented 1 switch board at a time. More detail will be released once the works are fully planned.

UPS B switch board continues to be manually monitored at all times.

Update from Volta/Verne:

We are aware of UPS B system losing supply twice this morning. This is still related to the issue we experienced over the weekend. A procedure is in place to reset the system. The fault is due to equipment on the system which was unforeseeably damaged during planned switching works. Replacement equipment is on order, and we are working as hard as we can to put a fix in place to prevent the system losing power until the replacement equipment arrives.
