I cannot view Stack Overflow on my iPad 2. I keep on getting the error:
This IP is only allowed to access our API.
To protect our users, we can't process requests from this IP address.
If you believe you have reached this page in error, contact us."
Now I have contacted and sent multiple emails to the email address in the link (firstname.lastname@example.org) but have gotten no response or help.
Ok, sorry about this but I found the cause of the problem. The onavo application does not uninstall cleanly. It leaves it's network profile in settings behind. This entry is hidden behind 3 or 4 other menu selections... I reset the network settings to factory settings and all is fine now :)
So if someone experiences this same issue make sure you don't use any software 'saving you bandwidth' that changes your proxy and network settings so that you are routed via their servers...
