Yesterday one of out hosting providers had a network hiccup.
We use a number of providers and something happens somewhere at least once a week.
Network blips are something one simply has to build around, redundancy & failover and all that.
Linode manages their issues well with frequent updates to their status page.
Employees participate in their IRC channel as well and are very responsive.
It was however speculated that the Fremont data-centre has more outages than others.
