On migrating a bot from trusty to stretch it's failing to connect to Freenode with
Closing Link: 18.104.22.168 (Too many user connections (global))
I can submit an iline for this, but since this is shared infra ideally an operator can do it on my behalf.
I believe the exec nodes did have a per-instance IP (at least long ago in history), the stretch cluster appears to use a nat gw or similar as I get the same across exec nodes (didn't dig into this very deeply to confirm however).
This is blocking migration the IRC relay workload off of trusty as external tools rely on the Freenode output.
Please let me know if you require any more details.
