CloudFlare Issues?

Sat Jul 18 00:46:58 UTC 2020

Did anyone see any collateral damage from this outside of Cloudflare? Specifically Azure?

I manage a very large site in Azure, and at the exact same time of the Cloudflare incident we saw a spike in traffic (like a DDoS or Bot), then followed by unusual hardware resource anomalies. We’re globally spread in Azure, but we only saw this in the US and Brazil.

Very coincidental, but possible.
