Google do a very good job of defining their SLAs.
In answer to your question, they'll accept evidence from your own monitoring system when you claim on the SLA. They pair that up to their own knowledge about how the system was performing, then make the grant.
Google are exceptionally good at this, from my experience. Far better than most other companies, who aim to provide as little detail as possible while getting away with 'providing an SLA'.
The SLA itself should specify the way availability is measured.
Down because email attachments are base64 encoded files written in plaintext into the body. So if those are not working, email itself is not working.

that was a bad example. i guess the comment was trying to say "how do you account for partial service degradations".
(i dont think SLAs are BS btw)
What if the majority of your users can access the service, but one of your BGP peers is not routing properly and some of your users are unable to access?
