DO NOT GO TO SOL, you won't to be able to access your toons there...Im waited for 3 hours and still cant get in.
I made the mistake of trying to go back to Sol System after the 1st freighter resque mission. Its been about 30 minutes while I wait for it to be available. If it full, it would be useful to have some sort of status message indicating your wait time, like you are number 564, now serving number 328. At least we would know that we might get in eventualy.
This ie in the pre-order phase, with maybe a third of the people who will try to get in the game for Feb 2nd. Probably most will be waiting forever and give up and return the game.
