With the RGL season active and more people at home due to COVID, the NA system is very full every night. We've also had to seriously look at the real server cost for NA, since dedicated servers are quite a bit more expensive in NA (I was paying the overrun myself, since serveme.tf is a non-profit by design).
That means I've had to raise the monthly goal in NA to cover the costs. That increased goal was already mostly being met, but I've also cut some costs by switching to cheaper dedicated servers, of equal or better specifications.
On the plus side, NA regularly has more active players than EU, so we've increased the amount of NA servers to 101. Depending on demand, COVID, and how the seasons go we will adjust the amount in the months ahead.
