It’s strange, I can't log on here - My ISP is TPG, my bro is on TPG also but half way down the coast. He has the same problems at the same time as I do. I have RDP'd into my server in Sydney they use Telstra and I can always get on using that (be it slow) anyone else want to list their ISP to see if it an issue there? It could just be a DNS issue with the new server, not propagating it properly or something.
I'm guessing site sponsors may be getting upset?
At the end of the day - when site works It’s WAY faster than it ever was before.
