See the reason for outage for this incident provided by our 3rd Party DDoS mitigation provider in London:

While performing routine maintenance to apply a config option for BGP at 2025-05-10 15:43:54 CET on one of our mitigation devices in Amsterdam, trying to address a relatively urgent issue, the BGP daemon lost connection to the control plane causing a short loss of routes and thus, packet loss on one of the mitigation devices. This is not expected to ever re-occur.

Issue has been confirmed resolved and traffic is not expected to be disrupted further.

RFO to follow.

We have identified a drop in ddos protected traffic in our London datacenter. We are investigating this issue.
