Hey @4wingtpt,
@gamerdruid is right, we checked the world and the world itself is running and lots of players play on this world. This suggests you have a local problem of accessing Tiberian 25.
In rare cases a certain version of a web browser causes problems, that's why I asked for the browser and version you use. THis would be very helpful to further investigate.
And finally, in a lot of cases the steps above solve the problem. That's why I suggested to do this first.
