Maybe I'm being petty, but it doesn't fill me with confidence when the ssl certificate on their website isn't even configured properly (valid for uberspace.de domain).

To clarify: seems their main site is on apache.org. But, their www.couchdb.org site (hosted on uberspace.de) doesn't have a correct cert.

For me I get a valid Let's Encrypt certificate that has blog.couchdb.org in its SAN list.

Their blog is hosted on Wordpress.com which seems to be using Let's Encrypt to generate one certificate for multiple different, unrelated custom domain names.

Maybe you encountered a bug where it served the wrong cert for a different batch of custom domains.

Update: someone has now fixed it.
