These might be entirely reasonable checks to see if the service is up
and running from monitoring systems. That's certainly not unheard of
and it'd actually be nice if we had a way to avoid having these errors
get thrown in that case. Even better would be making the monitoring
systems smarter, but that's not always easily done.
