Re: Routing Change in SE Mich.: No more router hostnames

Thanks for the awesome information. I'll make sure not to assume stuff! I don't mind that Chicago is the favorite handoff (although I know Merit and Comcast are directly peered elsewhere). It's the fact that hops 2 and 3 (in my original trace) no longer resolve DNS that bothers me. Maybe it's a temporary change, but any step that reduces transparency to the end user, IMHO, isn't a good one!

I've noticed slowdowns, no RDNS and RDNS additions in the last week or so. I'm guessing some equipment upgrades.

Specifically my route to Atlanta shows a new XE interface from GR to Pontiac (hop 5).

Also on my Chicago route I have an additional local hop (hop 5):

Tracing in the other direction shows an he interface in Pontiac and an xe interface in west Ann Arbor. I know routes aren't the same in each direction, so this may be useless information.
