[Comtec Announce] [Core Network] Maintenance window 19th September 2015 - Update 4

[David Croft]

Replacement hardware has been installed and the network is now stable.

Due to this issue, we will need to complete the tidy-up work tomorrow;
this is not expected to be service-affecting, but as we will be
working close to live equipment it is "at risk".

We apologise for the overrunning of this maintenance.

Regards

David Croft
