I think this is the old etcd certificate we used to use for etcd in codfw; since we've moved to etcd v3 we're using a new cert created with cergen:

$ openssl s_client -host conf2004.codfw.wmnet -port 4001 2>/dev/null | openssl x509 -noout -dates 
notBefore=Apr 25 07:11:49 2021 GMT
notAfter=Apr 25 07:11:49 2026 GMT

I am just going to revoke that certificate on the CA.

I just removed the cert from puppet.

06:42 < mutante> we got paged because the etcd cert in eqiad expired. nginx uses that

06:42 < mutante> etcd in codfw had already been converted to use cergen and etcd-v3 certs but eqiad had not
06:43 < mutante> eventually cwhite and myself figured that out and were able to create a new etcd-v3.eqiad cert matching the existing one for codfw but for eqiad and things have recovered now
06:44 < mutante> took us a while though and this should have warned us about expiry..not happen on a Saturday night unexpectedly
06:44 < mutante> will create an incident report but now it's too late here, almost midnight
