LeaseRig.net - rig down (critical) emails simply mean the customer pool is down?
Every time I get one, the rig is fine and LRP is still connected - customer pool went dead is all...
Is this a bug or should the email say "FYI - Customer's Pools Dead"
I have no other reports of pools causing rig down emails. That email should only show up if the api-connect poller times out on your rig, or if the lrp connection is dropped for a period of time.
I think I reported the same issue with Ticket #822.
That was with no working pools. If you use LRP (WHY DO YOU USE LRP) and there are no working pools, the miner should be considered critical down.
tl;dr don't dismiss LRP, fix it or host a proper a proxy server like other rental sites... please

There are miners that don't support cgminer API, which direct connect depends on. cudaminer/ccminer, all sorts of proprietary boxes (e.g. SilverFish), etc. Also saving the config file is broken in many cgminer clones that I've seen, so direct connect insists on saving that file in all kinds of inappropriate places with wrong values inside.
Uhm, the cgminer conf thing has been resolved for a long time. You just use -c to save the conf somewhere else and let the miner save the broken conf to the default location.
Your confusing "dirty network hacks" with the word "proper" above.
The proxy systems used by competitors are slammed repeatedly for the nasty code they use and the tricky methods implemented in order to make their systems work.
Besides, we are already doing a private beta of both of our remote stratum proxies.
As for fixing LRP, there are new developers working on it. But it's always going to be less desirable than API Connect.
