I've intermittently been getting "(Cannot contact the database server: Unknown error (10.0.6.42))" errors on https://en.wikipedia.org. This most recent time happened when trying to preview an edit. I don't edit much, but I've gotten the error a few times over the past week. It'd be nice if someone could check the frequency of such errors and examine what the underlying issue is.
Version: unspecified
Severity: normal
