Further to the replacement of our Primary UPS a few weeks ago some follup up work is required to install a management card and new batteries for the UPS. This is taking place tomorrow (10/12/2013).
During this maintenance there will be periods when the building will be supplied via raw mains and not through the UPS system. While this should cause no outage there is a risk as there is less protection than normal during this time.
We will update this post once the work is complete.
This work is now completed
