Reject rate is higher than GPUs (Hard to compete with < 0.1%), but even so the speed I'm measuring is valid shares only.

Why some shares are rejected?

Invalid shares should not occur since all submitted shares are double checked, by the FPGA and by the software.

Duplicate shares are possible since BTCMiner re-sends shares if pool server does not reply within timeout time.

Stales are possible too. (A stale reduction algorithm is planned for future).

BTW, BTCMiner counts only successfully submitted shares with a valid response as "submitted shares".

I can't tell you why !? It just came to my eyes when i was watching the statistics.

Starting to come back online. If the attack retargets the pool it may end up getting turned off again while we wait them out.

BTC Guild is a hot bed for DDOS. I hope this comes back soon because I'm freezing... My heaters are off. LOL

I was wondering why it was so cold in my room this morning! My heaters are off too! brrrrrrrr

I hate those script-kiddy-loosers so f******* much! What they really hope to gain by doing this? Idiots, ignorant SOBs.

Please stop bitching at those fools, they thrive on your anger.
Get ready for next time zombies attack. Setup failover, and continue mining elsewhere until the attack is over.
You'll feel a bit better, and sure won't loose heating in mid-winter.
Read the rules of Zombieland, and prepare accordingly.

Good luck!

Well little lower difficulty increment isn't bad thing but don't attack our pool lol

Server is still under attack, the second I boot up the server I can see the data/packet rates skyrocket into a completely unreasonable number. Takes less than 10 seconds from the time the server is online before it is essentially unreachable.

If the server can't recover in the next 12 hours I'll try to get the server moved to a different IP address so automatic payouts can be processed at least.

DDoS is distributed denial of service, right? Could someone refresh my memory on what this is and why it happens? Is that someone "attacking" your servers/IP addresses?

If so, silly kids and their pesky attacks...

Does it seem that these DDOS attacks seem to coincide with the difficulty adjustment day? I suppose it could be coincidence.

May be he is talking about stale shares ?

Was hoping after the huge price drops and overall network drops these kind of attacks would go away, but obviously not. Had a good run of stability ever since the PPS switch, but all we can do in the face of a DDoS is wait.

If you don't have backup miners, I'd recommend pointing to a smaller pool (I won't name any since most smaller pools can't handle a 500+ GH/s surge). If past attacks are any reference, it probably will be at least 12 hours before the kiddies get bored and point their zombie army somewhere else.

Throw some 500Ghash at Bitclockers.com and she will take it Cheesy

Stupid antisocial idiots.

Sorry to hear it, guess I reset my miners to backup for now.

Will check back in the morning, I guess.

Currently getting hit by a DDoS again, trying to come up with a solution right now (moving IPs or waiting it out).

Was just coming here to see if there was a reason behind the miners sitting idle.

Glad to see you're on top of it. Hope it gets figured out soon. I need the heat from my miners, to keep me warm at night. ;-)
