There are a lot of such issues recently on many major websites/services. Is it just me or are those more frequent than a few years ago?
However, this may be the result of increased dependence on centralized services which gain more and more traffic, which is more difficult to handle and even simple Regex rules (see Cloudflare outage recently) can break everything. To be honest, I don't want to ever be in charge of keeping such complex systems online.
