We were the first GSP to roll R10, so that helped

. I was testing by joining servers after the roll-out, and the only ones in the list were ours. I found that after I joined an empty server, clients would start packing in after just a few minutes.
Now that everyone else has updated, it might slow down a bit, but since the browser is much better now (it does actual pings, and it's a lot faster), that should put our servers regularly near the top.
