Following on from the previous power issues, we have identified some UPS equipment that was failing to perform as expected. As such we will be replacing the UPS equipment between 17.30hrs and 18.30hrs on Thursday 14th September 2006. This change will affect some co-located hosting customers who will be advised individually. We will also be exchanging the UPS that covers the following servers: pop, dns-cache1, and dial-gateway; a small period of outage will be required for the swap over. Please accept out apologies for any down time caused, but wish to assure you that the work taking place is essential.
