Hi hgr134,
Thanks for bringing this to our attention.
We're having a few problems with a number of websites at the moment due to some recent upgrades on our network firewall.
Since this was working for you previously, it confirms that this is a problem on our end rather than anything you're doing wrong.
Unfortunately there is no fix for this that we can offer you at this time, however we will raise this information to our Faults Team who is investigating the issue, which should help them ascertain the cause
An email is on its way to you now asking for more details
