The /etc/hosts file on your phone has aliased r.admob.com to 127.0.0.1. I had this occur when I used a flashed ROM on my phone -- the ROM defined a whole bunch of entries like that so I'd never get ads. Which was great until I was testing my own ad-enabled app :-)
Edit your /etc/hosts and take out that entry.
AdMob's server (like any high volume server) can take too long to respond sometimes. It is better that you design with failure like this as expected behavior.
If you think there is more to it than that. Post what you are seeing that makes you think something else may be going on.
