Sign up with Objective Uptime Inc. and tell them which vendors you have SLAs with. OU will monitor them on your behalf, compare the actual global availability to what's displayed on the vendor's status page, and if the outage exceeds agreed limits, OU can even automatically file suits on your behalf for breach of contract and misrepresentation (assuming the vendor's status page was showing all peachy).
