David et al.:
It's not down, it's being intentionally blocked in the hopes of
forcing the legacy razor-agents to rebalance under extreme load.
There is a long-standing bug in the razor-agents package wrt
discovery and cycling through the server lists. Older (but still
recent) agents properly retrieve the csl, but fail to pare down
(modify) the list when cycling through entries during connection
failures or timeouts. The consequence is a rather large body of
agents talking to one server, and only balancing to the others
when that one server is unavailable. Since most razor-agent
invocations are single-instance, the moment that single server
becomes available again all subsequent invocations stop falling
through to other entries on the list and swamp the first again.
Normally this isn't a problem; we've been dealing with it for a
long time and hopefully this will get fixed soon in a future
version of the agents. However, the razor2 rush after the
holidays is overwhelming wonder.cloudmark.com, so I'm closing its
port in order to force the agents to fall through to the other
entries on the list (which should (and seem to) be more
statistically balanced).
The best thing to do if this issue is causing you or your mail
service problems is to force your agents to rediscover with
``razor-admin -discover''.
FYI, this only affects the open-source razor2 agents.
Best,

p.s. Would you mind forwarding this to the razor-users list?
Sourceforge's anti-spam mechanisms have pretty much made it
impossible for me to post to it.
