Logs.tf has a good API. Both for uploading logfiles and reading the stats.
It uses TFTrue or F2's sourcemod plugins on the server side to add the extra information to the logs and upload the logs to logs.tf.

• All: Added !rcon chat command so the person making the reservation can execute rcon commands without having to remember the rcon password, yay for dementia!
  
• EU: Sent the server providers their share of the donations based on amount of time played
  
• NA: Sent tragicservers half of the donations for na.serveme.tf. No calculations needed when there's only 1 server provider :)

• All: Changed the way you find available servers. You now always go to the new reservation screen. After entering start+end times the list of available servers updates automatically.
  
• EU: People keep trying to use the beefy pipe of the VanillaTV servers to attack TF2Center http://en.wikipedia.org/wiki/Reflection_attack. To protect TF2Center, their server is somtimes firewalled on the VanillaTV servers. When the firewall is active you'll see a "not responding" error on TF2Center, please use another server during this time.

Because it uses the power lines for network connectivity. Works best if it doesn't need to cross breaker switches and such.

WiFi, especially the normal 2.4ghz type, is never going to be really reliable in terms of latency. There's too few channels, too many sources of interference and with multiple clients on the same network you'll get random delays.
If you have no other option than WiFi, get a router that has 5ghz support and only use the 5ghz for gaming.

• NA: Added donation tracker
  
• NA: Converted prices to dollars instead of scary+expensive European money.
  
• NA: Lowered prices
  
• All: Added per month statistics, showing the crazy growth :) EU vs NA

serveme.tf! :)

• All: Built an API, so other sites and programs can make reservations, lobby sites for example. Instructions on how to use in the README
  
• All: Allow multiple simultaneous reservations for donators again

• EU: Re-enabled the XenTF servers. Rebuilt/improved hardware, yay! They’ve had a namechange to “hopjb.eu” and there’s now 4 instead of 3!
  
• NA: Moved two extra servers to donator-only, to try and squeeze some dollars out of you yankees.
  
• All: Fixed the timezone offset in the timezone select dropdown.

gg!

• Donators can now upload new maps. These are automatically synced to all servers. For the EU system they're also instantly available for fast download when connecting to any of the servers, still need to fix a fast download for the NA servers.

Thanks for the great show both teams

• Added a dark theme, click the square in the top right to toggle.
  
• You can now end and extend your reservation from the server. Simply type !end to end, and !extend to...you guessed it, extend.

Mirelin, ever since he first picked up the medigun.
