Scheduled - During this period we will be performing maintenance on our STS in our Reading Datacentre. This maintenance forms part of our yearly planned preventative maintenance where each unit is checked for normal operation and consumable items are replaced.

No interruption to service is expected, however this should be considered an at-risk period. As part of the maintenance power will be transitioned between the "A" supply and the "B" supply and back again.

It may be necessary to place the units in bypass mode during this period - if this is the case then the STS will not be available and a reduced level of resiliency will be observed however each feed will remain protected by UPS and generator backup.

Scheduled - During this period we will be performing maintenance on our UPS in our Reading Datacentre. This maintenance forms part of our yearly planned preventative maintenance where each unit is checked for normal operation and consumable items are replaced.

No interruption to service is expected, however this should be considered an at-risk period. As part of the maintenance power will be transitioned to and from raw mains at times and the UPS is designed to do this with no loss of load and there will also be mains failure tests carried out during this window.

During these transitions and tests, the STS will still be in operation and maintenance will only be performed on one UPS of each pair (A+B) at a time.
