PEER1 runs a redundant network utilizing 4 Tier 1 upstream providers. One of these providers, Savvis, had a major network fault last night. I started getting reports from customers that they are either unable to access their server, or their server was unable to access the internet outside the PEER1 network. After a bunch of diagnosis, I was able to trace the issue to our Savvis transit upstreams in the east coast.
I then checked a very handy service called Internet Pulse, and discovered that Savvis was having network issues pretty much all over North America.
Fantastic. However, with the help of the Engineering department, we were quickly able to react, and redirect traffic out the other upstreams, avoiding Savvis where possible. Most providers, no matter how big or small, will have network issues, faults, and generally not nice stuff happen to them.. However what makes the difference between the decent networks, and the great networks (like PEER1) is the ability to react quickly to changes in the structure of the network and minimize latency, packet loss, and downtime.
