All major pools listed on mooncoin.info are down

Sure makes cheap Mooncoins at Cryptsy.
I shut my pool down as the mooncoind randomly starts chewing up all my bandwidth as well as CPU... the other pools probably got annoyed with that too.
You should simply upgrade your server, if it can't cope with alternating loads. If you followed the average hashrate of the MOON-mining-network, it went from 300 Mh/s up to 1 Gh/s and back over the last days several times. That is not easy for some pools running on a feeble server.
