On October 29th 2023, between 07:10 and 07:30 UTC, a small percentage of Pantheon sites started reporting downtime per internal monitoring. Upon further investigation it was determined that a single malicious site was receiving a massive amount of requests, which in turn overloaded certain internal services. This prevented other traffic from being served. The site was immediately blocked at the edge and put into maintenance mode due to its abusive/bad actor nature. We are actively working to reduce our exposure to this sort of incident in the future.
