links dont work for me either, thats one hell of a nasty page setup tho.. java links are just.. crap.
wonder how many non-techy users have reached that page and wondered why it didnt work? java just doesnt really work and isnt exactly installed as standard these days, which makes me wonder why they arnt linking properly, kinda messed up tbh.
still by the looks of it there are issues with their database server, if they keep the details on the same server (aka the data is stored on the same server which is required for your username and login details for email) then its pretty easy to guess why you cant login, still for it to go down on a holiday weekend is somewhat weird.. not to put the cat out amongst the pigeons but maybe its a hack attempt, its not uncommon sadly but there are only a few reasons a server would have issues, especially database ones.. tho thats just one possibility, others are quite innocent but regardless it looks like someone needs to SSH into the server and restart a module or two.
