[VoiceOps] Plivo Offline, Domain Expired; Out of Business?

Sun Apr 23 18:42:32 EDT 2017

Still priceless. If our application servers cannot access critical
resources from a carrier, regardless of the cause (network, application
outage on their end, domain went un-registered), I now know it isn't
working.

That still is priceless. Monitoring should tell you what, not why. Blackbox
monitoring (measure the experience customers experience) is wildly more
valuable than whitebox monitoring (a DB query took more than 10 seconds,
once).

Your metrics system should help you answer why, once you know that
something is wrong.
