Conclusion of the Feedburner latency test

[Macro error: Can’t find a sub-table named “scripting2”.]

Scripting News, the weblog started in 1997 that bootstrapped the blogging revolution.

It appears that it takes FB some amount of time to recognize a feed once its been registered, but that once it does, it's pretty close to perfect at caching a feed for 30 minutes before refreshing its copy from the original.

A table that reports on the test.

Notes on the test when it started are here.

Here's the original feed and here's the Feedburner version.

I looked for docs on how to ping Feedburner, but came up with confusing and contradictory instructions, none of which worked. They all got Java errors from the server. I tried pinging using their form and through pingomatic, neither of which had any effect on the latency.

I tried adding a <ttl> element to the feed, set it to 1 minute to see if that had any effect. I'll let you know.

Update: Apparently Feedburner ignores <ttl>.

Update: I turned the test off for now. ";->"
