OpenDNS acquires BGPMon and the future of route monitoring

Nick Buraglio of The Forwarding Plane comments:

For those that run BGP networks, BGPmon is often a tool they turn to for some really unique and hard to find information. Remember back in February 2008 when Pakistan Telecom “blocked” Youtube? That one was a really, really public example of something that BGPMon caught. BGPmon has been around for a long, long time. Quietly watching prefixes. Silently noting changes and reporting them to the ones lucky enough to know of its existence.
For those that don’t know how BGP works, I am not going to go into it too much other than to say that it is both the foundation that the internet is built upon, and one of the most antiquated trust models that exists in a world where most of the pundits are going on and on about SDN and network engineers being out of a job in 10 years. See, the problem with BGP is not that it is a terrible protocol. Quite the opposite, it is elegant in its simplicity and ability to be extended.It is lightweight and arguably the easiest of the routing protocols with the exception of RIPv2.

BGPMon is a big part of the network troubleshooting toolbox, and not just for engineers either. Several well-known monitoring solutions use BGPMon as a part of their information gathering. The pickup by OpenDNS means good things in the future for them.
