This is getting ridiculous .... most of my rigs have fallen over to the main non-regional url i.e stratum+tcp://stratum.bitcoin.cz:3333 BUT they are not registering any significant hash on the site dashboard though they are running OK locally.
Also, the dashboard has gone bonkers .... block duration is forever in negative time, block do not register on the graph etc.. I better head of to facebook and see whether there is any news from the horse's mouth.
Isn't it smarter to use the one closest to you? Just curious, I thought that was the whole idea servers in different parts of the world.
You did miss that .... I use the eu one but it kept failing over to the main url which I use as backup. Usually the software will keep checking the first pool for when it comes back online and reverts, in this case though, randomly, most of my rigs keep mining on the backup url (and it does not seem to be registering at the pool!). After 3+ hrs of this, I decided to point elsewhere until we can get some definitive info from slush.
