Scheduled
Colt will carry out planned maintenance affecting our 100Gbps London (LHR0) to Amsterdam (AMS0) link from 21:00 GMT on Tuesday 10 November to 03:00 GMT on Wednesday 11 November 2026.
Colt estimates up to 300 minutes of interruption to the link within this six-hour window. Engineers will replace an attenuator and recalibrate equipment in Amsterdam to address hardware degradation. The window includes time to revert the change if required.
Connectivity using this link may be interrupted during the work. We will provide a further update when Colt confirms completion.
