HTTPS requests end up twice in the udp2log pipeline for all data-centers. Once from directly from the nginx-s, once from the varnishes. For ulsfo, both entries in the log line get counted by webstatscollector, leading to double counting of ulsfo https traffic.
A corresponding fix at https://gerrit.wikimedia.org/r/#/c/156840/1 has been merged, but due to the pending weekend, and since Monday is Labour Day, it'll probably take some days until it gets deployed.
The fix is effective. The first good files are https://dumps.wikimedia.org/other/pagecounts-raw/2014/2014-09/pagecounts-20140902-180000.gz https://dumps.wikimedia.org/other/pagecounts-raw/2014/2014-09/projectcounts-20140902-180000
