None of my settings have changed, but this is how my hashrate has been these past couple of days...

Notice the past two days... a bunch of rejects and lower speeds. Any reason why this is happening?
Read the thread, its been asked 100 times. try using the EU server instead...and you expect h2o to come here and answer your question??? Its already been answered, now go read!
I've read every page over the last 100 or so pages. USEast server is the closest to me, which I use and have the Oregon (middlecoin.com) server as a backup. None of my settings have changed, yet my hashing changed drastically. At times it's where it's supposed to be (~6.5mh/s) but other times I have a ton of rejects and my hashrate drops down to 4.x mh/s...
I understand there were problems this morning with middlecoin, but that doesn't explain the last 2-3 days.
Had you of read the last 20 pages even, you would see that the solution has been to use the EU server. Keep using the USA ones, go ahead, keep at it
