Sorry about that - yes it was the 'http://' in the message - Steve did pass on your comment to me, and I said 'Ah ha!'
The reason you can access if the next day is because you're on a 'Dynamic IP' address.
Each time you connect to the internet you are given a unique address. Some people have static addresses (like us here) and some are given an address every time they connect.
There is a small chance you could reconnect using the banned IP address.
If you find you suddenly cannot see the website again - goto
www.whatismyip.com and make a note of the IP address shown.
Technical mumble jumble - sorry!
