With today's connection woes, I got a full day of:
Aug 22 14:46:56 miner cgminer[1679]: Testing pool stratum+tcp://mint.bitminter.com:3333
Unfortunately, not more info is given in syslog. Is this a cgminer issue that it didn't switch to the backup pool or is this BitMinter related?
I'm using CGMiner and it didn't switch over to the backup either, but thankfully I was at my computer when everything went down so I changed it manually.
