U(-verse) can't get there from here,no route to airportal.de

note to conspiracy theorists: It happens to be a minor enabler of an ATT-wireless competitor.

Can access www.airportal.de via:
1. Opera-Mini browser (akin to a poor man's proxy),
2. a (non-ATT) cell network.

Why just recently inaccessible specifically via [other browsers behind my] u-verse?

% nc -z -v www.airportal.de 80
nc: connect to www.airportal.de port 80 (tcp) failed: Operation timed out
nc: connect to www.airportal.de port 80 (tcp) failed: No route to host
% nc -z -v -u www.airportal.de 80
Connection to www.airportal.de 80 port [udp/http] succeeded!
% nc -z -v 81.169.145.156 80
nc: connect to 81.169.145.156 port 80 (tcp) failed: Operation timed out

another *.de for comparison's sake (81.91.170.12):

% nc -v -z www.denic.de 80
Connection to www.denic.de 80 port [tcp/http] succeeded!

Thanks.

I had a similar issue recently but reversed. With Comcast, I was unable to access »crypto.cat while I could with U-Verse.

I doubt it'll remain an issue for long.

It looks like a routing problem to www.airportal.de from U-verse. The Anycast DNS lists it at 81.169.45.156

For me it is lost at 12.81.8.69

Definitely a problem on the AT&T network.

From my office (1Gbps AT&T internet), my trace dies off after it reaches the PER address on AT&T.

If I turn on my Cisco ScanSafe proxy (proxies traffic through a Cisco datacenter), trace and webpage load up fine.

As a side note, I have an iPhone 4S on T-Mobile and I get 3G in a LOT more areas than the map would have you believe. Then again I'm not surprised as the site isn't even iPhone-friendly. So you must screenshot the information the site requires then either input the data when you get home or tether your laptop while you're driving.
