The above links is provided in Neighbourhood webservice description page. I tried other webservices and they are also failing. And If I go to http://ws.geonames.org/ the page is redirected to some other website. Just concerned whether the website has been hacked or what ?
BUT its very suspicious that ws.geonames.org redirects to the the iPhone apps webpage!
The only reason I can think is its a retaliatory effort, to send all the traffic that is currently hitting geonames servers and instead overwelm imob's webservers.
Another iphone application using the commercial services have realized that they were having a call to the ws.geonames.org domain in their code and disabling the domain stopped their application. As a quick and dirty stopgap solution we have had to point the domain to any server for a couple of hours. The server causing the troubles was the best solution without causing damage to someone not involved.
Sorry about all this confusion.
