You can reproduce one of this requests by using telnet as follows. Please note

[prompt]$ telnet 91.198.174.204 80

Summing up, somehow we are generating requests in the client like:
http://es.m.wikipedia.org/http://es.m.wikipedia.org/wiki/Wikipedia:Portada;
which, according to http are valid requests, those

Need to look at IP ranges as I looked at languages and wikipedia's for
geographic commonality and that might not be the best.

I take my prior comment back, this looks like a proxy issue not client issue.
Data
below for requests that match orghttp in the month of August thus far in
zero, mobile and sampled.
1. zero

IPs with most issues in zero are not the most used IPs so, again, this points
to a proxy issue.

Nuria, are you saying one of our proxies is causing this? Or is it some common
proxy software that many carriers are using that sets incorrect HOST value when
forwarding request?

Well, neither. By looking at the data looks to be caused by a proxy but I do
not think is common software as the percentage data affected seems pretty
small.

Parsing all zero.tsv* files i noticed a large number
of other strange items - highly broken URLs that still return miss/200 result.
I think we are missing issues here. I will address this

This problem is also present on sampled logs, mobile and api since records are
kept on stats1002. That means since about May 2013. I imagine there must have
been another bug fixed on this regard

--- Comment #3 from Kevin Leduc kle...@wikimedia.org ---
If you compare the number of occurrences to the number of lines in the file,
this seems to happen less than 0.025% of the time. This seems insignificant.
Could this just be corrupt data

Sure, we could ignore it, but i am worried if this could point to some bigger
issue. Parsing all zero.tsv* files i noticed a large number of other strange
items - highly broken URLs
