I'm curious as to what sorts of response rates those who have been

this have been seeing contact rates similar to ours.

At DE-CIX (www.de-cix.net) we have two route-servers (resilient setup).
We were not really actively contacting peers (i.e. did not really press
them to activate MD5).

Our figures (counted per AS not per peering as we have double peerings
both on our side as well as on customer side having two+ routers) are:

 120 peerings
  21 MD5 peerings

 ratio: 17.5%

Better than expected. I told a friend that MD5 peerings would be <10%.
Now I have been pretty vocal about the whole MD5 thing, but I have to say that route-servers are probably not the best indication of MD5-ness. Session which pass traffic get a little higher priority at most organizations.

Unfortunately, my organization was not passive until we got to see what the threat actually was, so our numbers are not useful. Would any traffic-carrying-organization care to discuss their numbers?

And anyone want to admit seeing an RST-style attack? Any attack which MD5 would have blocked?
