It looks like there has been a change in the DNS for wurfl.com and t.wurfl.com went lost with it.
I think t.wurfl.com was a great resource and I’ve seen a lot of hits without much publicity.
I’ve decided to keep it up and register a new domain for it. Some of the names I would have wanted to use were taken, already so I’ve gone for logme.mobi. Hit it with your mobile and you’ll get everything you used to get with the old t.wurfl.com. logme.mobi/query is still there, of course.
Let me know if you see any issues, I quickly fixed the URL’s, but maybe some links are not fixed, yet. Allow a few hours for the DNS to propagate.
