Apparently the problem is that the server their main site is on can't handle so many people on it at once and it keeps ending up crashing. In turn, Chris Roberts set up a Kickstarter today with a $500k goal to supplement the amount that's coming in on the main site.
Here's the link to the Kickstarter:

$79,957/$500,000 so far, after about 8 hours up.
Here's the link to the main site, with counter:
http://www.robertsspaceindustries.com/star-citizen/
$1,046,566/$2,000,000 so far.
I don't think 2 million should be too much of a problem to get to, considering that word keeps spreading.
