DWDM Backhaul Upgrades

Wednesday, 15 May 2 hours

The maintenance is now complete. Thanks for your patience.


The scheduled maintenance is now underway. We'll keep you updated on our progress.


We're carrying out some MUX upgrades to enable more capacity between our London datacentre sites. There will be some brief 30-120 second periods of instability when connections are broken/made each time, a maximum of 2 times, between 21:00 and 23:00.

Apologies for any inconvenience caused by these essential works.

This is the last window in the upgrade programme.
