When I click the button, a ticket details screen is shown, complete that then it just switches back to the homepage. Interestingly the URL says ‘support…NewRequest’ instead of the homepage URL, but the page is just the homepage.
I’ve tested this with adblockers on and off, with both Firefox and Edge browsers. My broadband is working fine - all other websites load correctly.
So, yes it is - effectively - offline at the moment.
