We apologise but are aware of a number of leased lines that have dropped because of a hardware fault on a core switch in London.
We will have this restarted within the hour and will be replacing this switch with a new one overnight. More status updates will be posted here.
[update] The initial issue was resolved before 6pm and the replacement hardware was installed in London this evening. This is being monitored but we hope this will resolve the issue once and for all
