@Ipsum: No that's not related to this. 

@JPB: When blocks are paid out, older shares that are no longer eglible for future payouts get deleted by the server.

Hashrate updates have been resumed.

Miner hashrates are currently not updating which is the subject of this post. Balances will update when the next block is fully confirmed. Which pool are we talking about?

Bump

True. Announced it here on the support site and on twitter. Operating under stress right now. Sorry.

It really doesn't matter to which port you connect because all ports are using vardiff to dynamically adjust difficulty up and down according to your hashpower. If you connect to high-level port and are submitting shares to slow, your difficulty gets adjusted down until it fits. Chosing a lower port only means that it will take less time to adjust your difficulty.
