rate-limit and Facebook IP's

[Reindl Harald]

am i the only one facing all day long serveral facebook
networks hit RRL on both nameservers? for me there are
only two options to explain that:

* facebook is too dumb to cache responses (TTL a day)
* that's part of a well distributed amplification trying
  not make much noise on the single involved servers

interesting that this is ongoing for many months
