The day before yesterday, Saturady 26th, at around 5:15pm CET Star Wars Battlefront 2 Servers weren't accessible.
It looks like Gamespy is finally shutdown.
But you can continue playing SWBF2 MultiPlayer!! There are three ways given on our "HowToContinue" part, just check it. We do recommend GameMaster, it's the easiest way for now.
Short Tutorial GameMaster:
Download the file from the link (tip: see HowToContinue)
Extract the downloaded files with WinRAR or 7-Zip
Copy the ".exe" you need and put it into your Star Wars Battlefront 2 GameData
That's the ".exe" you now can play online with.
