[Bugzilla] Is Bugzilla down?

Hi,

It seems that Bugzilla (https://bugs.llvm.org/) is down, when I using
the search engine.

In case needed, this is full log.

For help, please send mail to the webmaster
(llvm-admin@lists.llvm.org), giving this error message and the time
and date of the error.

Looks like it’s working again? At least, I don’t see errors on the front page or doing a text search, or viewing bugs currently.
