Go on viclou , try to make it below #100, you can even ask the user from your city to contribute. any way who owns grd.net.pl i find that it is a status web site for many web hosts this is for http://x10hosting.grd.net.pl/monitor/ and much more.
The same problem was there for me too Viclou, stgeorge you can check this monitor to check the sever status in various ports http://heliohost.grd.net.pl/monitor/ , try to access when things show green.
but i can see dot tk office is in london and the admin of the dot tk support group in facebook is also lives in london, but i saw that this island is near Australia in maps.
yea i used to check that daily, that is why the site is ranked #93 in calicut by alexa http://www.alexa.com/siteinfo/grd.net.pl# , my city and it has regional rank only in india.
you account is not suspended it is queued it will take 24 hours to get up. you can check that after 24 hours. if you still find this try clear you cache
