Nor can anyone who peers with the above; InterNAP theoretically has a
better chance of getting good service, since they're a paying customer.
That's how their business model goes, at least.

SLAs are rarely worth the paper they're printed on. If you do not
design your network/services/whatever around the *expectation* that your
carrier will fail, you're in for a rough ride. What consolation is a
