Probably the php security urgent updates

FWIW, there has been a major security flaw announced in PHP so worldwide a large number of PHP based websites have been taken down as a precaution until they can be patched. I can only assume gpstc is one of these, as its PHP version is quite old.

I've looked at what's involved and it's definitely doable (I'm running a patched version of the current GPSTC website right now having applied the patch myself) but I expect the site will be offline for at least a day or two to get it sorted out. And I would not be surprised if Ben is working on other sites that have the same issue.

Give them some space to work it out, there are a vast number of affected websites around the world, and I am sure that free-to-use ones are lower on a lot of people's priority list.

(The good news is that a new non-PHP version of GPSTC is just about ready to go, so watch this space.)

There has been much activity behind the scenes and we are expecting teamchallenge to be available from around 9pm AEDST Saturday.
This unplanned outage has allowed us to move the site to a new host, so we are looking forward to announcing some changes very shortly.

Currently it is not possible to email teamchallenge directly. However the contact form is working or you can message on seabreeze.

Super work crew. However KA for me is still not sending sessions to GPSTC like it was before this. Using Apple and tried both phone and desktop.
