Comment (by ryandesign):

 When the internet connection that build.macports.org uses is down, as it
 was today, and on May 31, and on May 30, there is no way for it to provide
 a response.

 If you're suggesting routing all build.macports.org web traffic through
 another server on a different internet connection so that it could provide
 a message when the real server is unreachable, which server would we use
 for that?

 Conceivably we could use Braeburn, the server that powers www.macports.org
 and trac.macports.org. But I'm not sure if it has the capacity to
 accommodate that additional traffic. And it is in Germany and the
 buildmaster is in Texas. I'm not sure if introducing additional network
 delay to all requests is best, since people already complain that it
 responds slowly (which is both because of limited upstream network
 bandwidth and the amount of time it takes buildbot 0.8 to respond to some
 types of requests). It also introduces an additional point of failure. I
 usually keep a close eye on the buildmaster and know when it is down and
 what I need to do to get it back online, but that changes when additional
 servers outside of my control are added in.

 When I shut the servers down in anticipation of a thunderstorm and
 possible power outage, I leave the internet connection and router on, and
 the router could conceivably act as reverse proxy to provide a message
 when the backend is down. It might also be nice to let the router handle
 TLS and certificates. I did attempt to set that up about a year ago but
 didn't complete it.
