Hurricane Electric is a big component of our standard network -- we have a few 10GE pipes to them and generally see very good performance. We have other providers as well, and the network is fully n+1 redundant and does not rely on any single provider in anyway. We can -- and have -- withstood provider outages that have lasted several hours with no impact to our uptime.
