Just standard ISP here also.
Either they have an over active firewall installed on their server that has started to block IP address ranges it shouldn't be or they have another server configuration issue that is causing some visitors not being able to access their site. I can't remember how long it has been going on but 2/3 weeks at least for me at least.
If the IP address I have posted is correct everything is ok at my end so it is a fault either with their server or getting to their server.
