Im having issues using the site. Attempting to load the site will either time out or take ages to load but wont be able to do anything but look at the homepage. Attempting to create a plan or load one will time out.
Ive seen a reddit post from someone else in the same country as me (Australia) having the same issue.
I’ve got a similar issue as you, also in Australia.
In my case, I can load SimBrief using mobile data (Including hotspotting my PC), but otherwise I am unable to load the site at all, regardless of the device.
