Weirdly enough, we have received a handful of bug reports in the last
24 hours about unexpected disconnections:

- https://github.com/psycopg/psycopg2/issues/1078
- https://github.com/psycopg/psycopg2/issues/1079

None of the OPs haven't specified their network configurations though.
A similar report a few days ago
(https://github.com/psycopg/psycopg2/issues/1066) had Azure to blame.
