Starcraft 1, many people only can join few games

Hello, we are a crowd of friends and usually have fun with starcraft 1. To be precise, we love all the blizzard games :). Unfortunately, there is one issue occurring recently. In the pas, any of us can just create a public game and all the others are able to join. However, since a few days ago the situation becomes very uncertain… sometimes only a few people can join the games created by some particular players, but the others are not able to. It seems something is paring between all the users. After re-login, the paring seems to be changed, but just like before, it still seems not all the games are available. We also notice that the number of users online is becoming less than before. So people may meet the same trouble as us. We hope blizzard service dept can confirm this issue and help to fix it. Blizzard is always the best game company, many thanks!
