Re: [hobbit] grouping methods

Yes - I have that setup with customers' routers and CPEs.

The real problem is when, for example, 3 servers in one data center in
New Mexico lose connectivity with us in Ohio.  Then I get 3 SMS
messages on my phone, followed by 3 more when it comes back up.

It would be very convenient to have 1 messages saying this, that and
another thing went down in the last 60s.
