Who or what is SUDA in Facebook feeds?

Question

This comment appears in some Atom feeds from Facebook:

<!-- SUDA was here.  10.36.217.112 -->

What does it mean?

If it's only some feeds, is there anything that the feeds have in common or what's different about these feeds to the ones that don't have this comment?
I think I'm only looking at feeds of Walls (possibly other Pages). All of them seem to have it. Here's a Lord of the Rings example: facebook.com/feeds/…

Disclaimer: This is speculation because I can't find a confirmation, but here goes...

Just based on a couple of things, I'd say it's a marker entry that some kind of cataloging process internal to Facebook puts in.

The Suda or Souda (Greek: Σοῦδα) is a massive 10th century Byzantine encyclopedia of the ancient Mediterranean world...

All the sample entries that I can find use an address on the 10.0.0.0 subnet which is a private network. If it is a marker entry and the IP is the address of the system entering in the marker then it's internal to Facebook as it's a private IP.

Well, there are a few possibilities.
