I guess the only question left to the general community is whether or not there are others who are now pretty much unable to use Eligius reliably, as it my case. I mainly want to know this out of curiosity. i hope that others are not having the same level of difficulty connecting and using the pool without incident. i don't wish that on anyone except maybe the odd troll or two.

My antminer S1 is configured with the exact same eligius details for primary and secondary and then I have a different pool for the third one. Over time I notice that it seems to "leak" hashes to the second one, and very occasionally to the third one. But the third one gets like just a handful of diff 128 shares in a few days time. The fact that it goes to the second pool configured, which as I mentioned is identical to the first, is strange. I am thinking it sees some sort of hiccup and switches but since the second pool is identical to the first that "hiccup" must be short indeed since it is then able to mine on the same address at the same pool as the primary. I also like how these things switch back right away if the primary pool is available.
If you are seeing lots of switchover to backup you might try just configuring the backup the same as the primary and see if it actually keeps it mining on eligius.
I had some other smaller miners (asicminer cubes) setup on eligius too but I never configured a failover on those and they seemed to do just fine with the bfgminer proxy.
