MOON withdrawals were delayed today because there was unprecedented withdrawal demand and I was without Internet access for several hours (traveling).
Unfortunately I cannot predict when withdrawal demand will peak (If I could, I'd be a trader, rather than a pool op). I'm also not willing to leave more coins in the hot wallets where they could be subject to theft. MOON payments are going out now.
That's how it always works. You're right in front of the screen monitoring things and everything works fine. You decide to head out for 15 minutes, that's when everything goes to hell.
