The data used for most of the public servers is scraped from the Byond page. Relying on Byond means we're affected by their server downtime (no page, no data), but we will automatically discover any new public servers.

All private servers, and some public ones, are being polled directly for data. That means a list of private servers have to be maintained manually, but we're not affected by any downtimes (as long as the game servers themselves are up and running). This is usually a more reliable method, but it's more expensive to run since we have to send multiple network requests (instead of one to Byond).

Both methods can be affected by spoofing attacks, done by bad servers, and so there's no way to guarantee that the calculated stats and graphs are 100% correct.

But then again it's just some silly numbers for a bunch of games.

Source Code

This is a open source project running on Python and Django (for the dynamic web stuff), a little Go (for some behind-the-scene scripting) and some gnuplot (for some ugly but interesting graphs).

The source code itself is hosted at github.com and is open for any and all contributions.

Bugs

Better colors for the warning/offline server notices.

New features

Show note about data source for each server (scraped/polled).
Rewrite the whole update script to go.
Show fancy web stats from the web server logs.
Summary page showing overall stats for all servers:
- time since since latest update
- time to run update
- no. of online/warn/offline servers + graphs
- total/average no. of online players + graphs
- log of recently added/removed servers
- the no. of data points since start
- age of oldest data point?

Suggestions

Frontpage of some sort?
Page to send in requests to add new private servers?
Player growth rate for each server (+/- compared to avg.)?
Use some kind of banner/logo?
