This morning, monitors alerted our team to a high-volume, automated vulnerability scan on our Washington DC 1 platform (paas1.wdc).

This is a fairly common annoyance for all web hosts; however, there was a configuration issue with our server-side firewall, and this allowed the attack to continue long enough to affect some customer sites due to the volume of requests.

We have fully mitigated the issue, and all sites are operating normally at this time. There's no action required, and no sites were at risk of harm.
