There was a problem y/day with the server. The host company confirmed an attack had been made on another website being hosted there. They acted quickly to sort this and we were back on line st 8.30pm.
Not sure when the forum went down, first I knew was around 6pm when I got home from work.
Uhm, interesting. I have had another site hacked with the flag but this was with a totally different host company! Will look into all of this, thanks for letting me know.
