Found this tribute to CoH webpage, which is nicely done but so depressing to read:

Also, if you didn't already know, there's a program called Titan Icon, which gives you a way you can log in and run around in Paragon City and the other places in the game. There's no one to talk to or fight, but you can look around. Also depressing, but it's kind of nice to revisit old haunts sometimes, even if they're deserted.

Finally, if you want to see the spirit of the game find a new life, consider supporting Missing Worlds Media's Phoenix Project. I think they've got the best shot at building a viable successor. They're planning to launch a Kickstarter on September 8th of this year.
