Errata: WMF traffic logging service suffered from server capacity problems in Aug/Sep/Oct 2011.
Absolute traffic counts for October 2011 are approximatly 7% too low.
Data loss only occurred during peak hours. It therefore may have had somewhat different impact for traffic from different parts of the world.
and may have also skewed relative figures like share of traffic per browser or operating system.

From mid September till late November squid log records for mobile traffic were in invalid format.
Data could be repaired for logs from mid October onwards. Older logs were no longer available.

In a an unrelated server outage precisely half of traffic to WMF mobile sites was not counted from Oct 16 - Nov 29 (one of two load-balanced servers did not report traffic).
WMF has since improved server monitoring, so that similar outages should be detected and fixed much faster from now on.
