Valve has promised to release SteamPipe for TF2 some time today.
What this means for you is a 20-30min conversion, where all your file structure will be moved in /steamapps/ and the .gcfs files will be converted to .vpks (like for DOTA2 and L4D). The conversion should provide faster downloads, game boot times and map load times among other benefits. Your custom UI or other modifications will most likely be moved to a new folder called /custom/ or will be erased. Your UI author (or yourself) will need to update his/her work for SteamPipe.

However, for us server operators, it's not as simple. We will need to make a fresh new install of each of our dedicated servers to work for SteamPipe. Obviously, we should notice the same improvements as clients (even better in some cases), but it will take a lot more work.
I've already started the conversion process and I have all the requires files to launch. However, we still have to wait for Sourcemod and Metamod devs to update their plugins. I'm also expecting a lot of crashes/bugs once SteamPipe is live.
That's why I'm asking you guys to be patient while we find out what's broken and what needs to be updated or removed. I'm expecting some downtime today (if Valve actually releases SteamPipe), but we'll do our best to bring the servers back online as soon as we can.
If you do notice crashes or bugs or things missing (such as donors features, etc...), please let us know either through the forums, PMs or email.
I'll keep you guys updated through this thread and ShoutBox.
