I have used crt.sh for some time - and it recently started to show 'bad gateway'.

The interesting thing was doing company name matches for the certificates.

Looks like it's not just you.

Every now and then the crt.sh web interface gets a bit overloaded and has to
take a brief siesta. The service as a whole appears to still exist, as the
direct database access is still working.

This mailing list is not for crt.sh :)

There is one already for this, please use it:
