There is no load balancing. btcguild.com => US central server, AFAIK.
Exactly. In fact, for several days there was a message on the main BTC Guild page saying NOT to use btcguild.com as US Central was overloaded.
It was setup to do "round robin" load balancing [presumably passing out an address to the least loaded server ... not sure if it had any intelligence to know which servers could handle more load than others]. I remember the message about it pointing to central. I haven't seen it on the site recently though, so I assumed it was back to doing what it should be. Either way, Central has always been the best for me anyway.
He turned it off because it couldnt handle the connections.
