Money's not the only factor, they're also limited to OVH's work hours and work speed. I've seen games which don't host their own servers go down for a week without the issue being resolved simply because the hosting company's support was slow. It doesn't help that this happened on a weekend.
It IS something they should have considered, though. They're not entirely without fault. You can see kickstarter games' funding drop slightly after the date has passed, because people inevitably pull their money back out of the pot. Star Citizen tried to edit their terms to stop people from refunding after a certain date because backers who put in tens of thousands of dollars were threatening to take their money back.
I know this isn't a perfect example given the difference between the two systems, but this happens and any developer who uses other people to pay for their services ought to keep it in mind. It's a bit irresponsible to cross your fingers and hope for the best, because people don't always act their best, as we've just seen with this $2000 donation being charged back.
