No it doesn't. The amount of false alarm alerts you can get with internet based monitoring is more than 0. You could have a BGP route break things for one ISP your monitoring happens to use. You could have a failover event happening where it takes 30 seconds for everything to converge. I have multiple monitors on my app at 1 minute intervals from different vendors and ALWAYS a user will email us within 5 seconds of an issue. It's not realistic for a company to have automatic status updates trigger things without a person manually reviewing them because too many things can go wrong on the automatic status update to cause panic.

Most paid status monitoring services cover BGP route problems and ISP issues by only flagging an event if it's detected from X geographically diverse endpoints.
For the 30 seconds where you wait for failover to complete: that is a 30 second outage. It's not necessarily profitable to admit to it, but showing it as a 30 second outage would be accurate

Forgot about that centurylink BGP infinite loop route bug they had where it took down their whole system nationwide. A lot of monitoring services showed red even though it was one ISP that was done.
