We located the problem to be a private transport link between AMS and LON had caused the drop due to issues outside of our control. The resulting drop was because of the traffic shifting over. As a result of the private transport link failure, we have switched the mode of traffic for this transport, and do not expect it to occur again, however we are monitoring the situation in the event it does. We have also linked this private link to a few other recent small drops in the EU region (unrelated to the last status post which was a hardware issue), and apologize for any impact from that.
In regards to network stability, our London PoP will be undergoing an upgrade to improve a routing appliance constraint, and furthermore we will be implementing increased redundancy across all PoPs in the near future to increase resiliency during both planned and unplanned outages.
