Does Synapse ever stop trying to send events to dead servers?

[aaronraimist]

It doesn't seem like Synapse ever stops attempting to send messages to servers which are no longer online. Synapse should figure out that some servers are down and if they are continually down for multiple days then Synapse should stop attempting to send events to the server or back off exponentially. It seems like this could improve performance at least a bit and reduce the amount of logging for people on WARNING.

After #3765 it will be a bit easier to detect dead servers but for now Synapse needs to figure it out in its own.

it does (or at least, is meant to) back off exponentially.

I'm going to close this for now then. I haven't done a lot of studying to see if it does or doesn't. It just seems like it doesn't.
