There is no reason on God's green Earth for the server capacity problems during Early Access, as SE had access to the amount of copies pre-sold and should have had capacity in place in advance to support at least that many concurrent connections. For God's sake, they bragged about pre-selling a million plus copies! And then to carry to release, again with sales figures in hand the datacenters should have been ready to handle at least the number of copies sold to that point, plus a padding figure to handle the sales from that point on.
Whoever made the decisions on capacity should be fired, and in practically any other large-scale rollout heads would be rolled out and stuck up on pikes for undercapacity on the scale ARR is experiencing. Entire IT departments and IT department managers have been canned for screwups of this magnitude. Over a million copies pre-sold yet only having the functional capacity online for only about 300k concurrent players? What idiot(s) made that call and why are they still employed?
