The servers for 'stratum.btcguild.com' are actually with OVH in Canada now. I've had to diversify in recent months to make DDoS attacks less effective (no single point of failure for all servers like the previous colocation). I'm working on diversifying further with colocation in multiple datacenters. Until recently the pool was not earning enough to pay for multiple colocations, and I had to wait to see if this was going to be another $32-40 bubble followed by another rapid crash before I invested money in buying more hardware and paying the much higher costs to colocate.
@eleuthria,
Slush lost at least 600 BTC from his hot wallet due to what was apparently an attack by an insider at OVH.
I'd seriously consider changing away from their hosting. You might want to ask him what HE thinks about OVH these days.
