[dns-operations] Distributed Monitoring

We do a combination of Catchpoint and VPS for monitoring DNS.  The VPS are just to cover areas where we want more specific monitoring (e.g. trying to watch what’s happening with specific upstream providers or needing better density in a specific geo.)  Initially it was all VPS monitoring from about 6 or 8 different locations, do a bunch of digs, send an alert if x% of them fail to resolve or are incorrect. Catchpoint came later but does basically the same thing.

BGP monitoring is done internally (OpenDNS, now a part of Cisco, owns BGPmon so needless to say we use that to monitor our prefixes.)  Really helpful to make sure your packets actually flow to you ;-)
