I want to note that puppet apparently fails at the etcd host.

During investigation, it appears that it fails everywhere, not just on etcd.

Caused by: org.postgresql.util.PSQLException: SSL error: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

this happens constantly at the puppetdb03 host

there's also https://gerrit.wikimedia.org/r/c/operations/puppet/+/739266 happening semi-recently, touching PKI. CC'ing @jbond.

this is in puppet.log at the puppetdb host. It appears to make some changes requested by the pki puppet profile, and then it starts to fail.

The puppet failure on the second deployment host is:

Web requests to the Beta cluster (e.g. https://en.wikipedia.beta.wmflabs.org/) are currently broken with the same message, but were still working 2 hours ago (otherwise this CI build, which makes requests against Beta, would’ve failed).

Interestingly, upload.wikimedia.beta.wmflabs.org is still working. https://commons.wikimedia.beta.wmflabs.org/wiki/ and https://en.wikipedia.beta.wmflabs.org/ are broken though.

T296000 is just a coincidence or could there be a relation?

upload.wm.beta.wmflabs.org requests are not served by MW directly, so MW failing to load parts of its configuration from etcd does not affect it.

Coincidence.

Within the context of the Beta Cluster this is UBN as it's blocking all use.

Note the root cause is T296127, which already is an UBN.
