Overnight we detected errors on a switch in Telehouse which provides connectivity to London-3.
Following further tests today it was determined that a serious fault had developed with the hardware and engineers were despatched to investigate further.
A faulty unit was identified and replaced at 21:58 this evening which will have resulted in a brief flap and loss of connectivity for some customers connected via London-3 (TeleHouse North)
We would like to apologise for any inconvenience caused by this emergency maintenance this evening.
