In order to redeploy webstatscollector, both the filter and the collector process need to be restarted, which causes the messages that have already been collected during this hour to get dropped. To minimize message loss around the deployment of the fixes for bug 66352 and bug 71790, we waited until http://dumps.wikimedia.org/other/pagecounts-raw/2014/2014-10/pagecounts-20141015-190000.gz http://dumps.wikimedia.org/other/pagecounts-raw/2014/2014-10/projectcounts-20141015-190000 got written to disk (19:00:30) and then restarted webstatscollector's filter and collector. On 19:02:30 both filter and collector were running again. So total loss is <2 minutes.
Note that this only affects the files in http://dumps.wikimedia.org/other/pagecounts-raw . The files in http://dumps.wikimedia.org/other/pagecounts-all-sites are not affected.
