Hi,

On Jan 13th 2015 between 22:20 and 23:18 UTC (~1 hour) stat1002 ceased receiving TSV data from udp2log for the following data streams:

- Mobile requests stream
- Pagecounts-raw
- Requests stream
- Zero requests stream

The reason for that were routing problems in the firewall introduced by a change to the way iptables rules are created for udp2log.
The problem was quickly resolved.

Here is Phab task: https://phabricator.wikimedia.org/T86973

Apologies for the late email,
Marcel
