Saw on PlanetUnreal that the official Unreal Tournament site has word from Mark Reign that the 28.8 modem is again working in the Epic offices and that the Unreal Tournament Demo may yet be released today as planned:

The office internet connection seems to be back. I'm continuing to upload a new build for 3DFX and GT to test from my house just in case but Steve and Tim are heading back to the office. Barring any further minor bugs we're confident the demo release will go ahead as scheduled late today.
