A lot of stuff on the Internet is currently broken on account of a Sectigo root certificate expiring at 10:48:38 UTC today. Generally speaking, this is affecting older, non-browser clients (notably OpenSSL 1.0.x) which talk to TLS servers which serve a Sectigo certificate chain ending in the expired certificate.
