i've had a few disconnects from the pool today too. i've seen it disconnect at least 4 times in the last hour.
im in the UK so perhaps this is a factor. please add me to the list of Euro users waiting for a local node.
I'm in the UK too, and I have Clevermining set up as my primary pool, and an automatic failover pointed at a backup pool. I'm seeing coins coming through from my backup pool, so there must be some disconnects going on.
...and yes, reject rate doesn't appear to be any better than yesterday.
