we don't use aws we host our own servers at Extremepool. But it looks like the payout issues started with the new round of pool updates.
Right now it appears as if, and if someone mining @ extreme that hasn't received payout can confirm, that the coins are not missing there stuck in pending.
Your coins are safe and I am working with the open source pool dev regarding this issue. Until then your coins are safe. If I have to I can manually push them.
Thnx for the update, but I have some coins "missing" besides those that are pending now because I mined for 18 hours @ 2khs and got only 40 coins sent to me manually
