Real User Monitoring Intermittent 404 errors returned from web servers

We have confirmed the root cause of the issue being a huge increase in RUM traffic, and for the time being put in place specific blocks to keep it under control. We have restored RUM to full operation now and the majority of RUM checks will continue to function correctly. We will notify you directly of any specific RUM checks that are being limited.

In the meantime we are beginning to work on long-term improvements that will better cope with similar peaks in traffic.
