When attempting to view the request url above, the trace below is experienced.
The key parts seem to be:
pymysql.err.InternalError: (1226, "User 's51469' has exceeded the 'max_user_connections' resource (current value: 10)")
The above exception was the direct cause of the following exception:
pymysql.err.OperationalError: (2003, "Can't connect to MySQL server on 'enwiki.labsdb'")
Not sure why this is happening but this may have high traffic at the moment due to a mention on https://en.wikipedia.org/wiki/Wikipedia_talk:Arbitration_Committee/Noticeboard#Edgar181_desysopped
