Comment (by cohosh):

 Looks like there's definitely some blocking happening, but it wouldn't be
 happening at the bridge. Either it's happening between the client and the
 broker or connections to snowflakes are failing. I'll see if I can track
 down what's happening with our VPS. Some observations:

 - We don't log at the client by default, we might want to consider adding
 some extra logging messages for snowflake (perhaps using the new LOG
 feature in the pt-spec?) so that we can pin down how far the client gets
 in the rendezvous before the connection fails

 - ` 1 connections died in state handshaking (TLS) with SSL state SSLv2/v3
 read server hello A in HANDSHAKE` suggests that we might want to consider
 adding uTLS to snowflake.
