Hi PA Team,

I have a notification sytem in place which checks for new notifications on a pre-determined interval. I have the application setup to email me of any errors and just received the following: (2005, "Unknown MySQL server host 'xdev.mysql.pythonanywhere-services.com' (0)"). I just checked my application and everything seems to be working fine, but I'm unsure of what I need to do to prevent this from occuring in the first place.

Any ideas on what would have caused this or what I can/should do to prevent this from happening?

Thanks for your help!

I just received this notification too. And my site is showing a server error (500).

That's strange -- where are you seeing those errors? Are they still happening? Can you connect to your databases from the PA Bash console as shown here?

From my error.log:

File "/home/absencelog/.virtualenvs/absencelog/local/lib/python2.7/site-packages/MySQLdb/connections.py", line 179, in init super(Connection, self).init(args, *kwargs2) OperationalError: (2005, "Unknown MySQL server host 'absencelog.mysql.pythonanywhere-services.com' (0)")

This occurred suddenly last night (I haven't changed my code in many months). But this morning it seems to have resolved itself. I can connect to the database through the PA Bash console as well as through Sequel Pro on my local Mac. I don't know what happened last night, but I'm nervous that it will happen again.

Where am I seeing those errors? I've attached the traceback below but it has to do with my django app's sessions.

Are they still happening? After posting the first time, it occured another 5 times yesterday. I haven't seen it happen today.

Can you connect to your databases from the PA Bash console as shown here? Yes, and I verified it was working myself by logging into the site.

Looks like some network glitch. We will have to investigate.

Great, thank you PA team!
