Betreff: [WikimediaMobile] Spike in mobile editing errors
An: "mobile-l" <mobile-l@lists.wikimedia.org>
Cc: "mobile-tech" <mobile-tech@wikimedia.org>

I noticed this spike [1] in editing errors on mobile so have investigated it.

These were the types of errors occuring on that day [2]
NULL 23
autoblocked 5
badtoken 8
blocked 88
editconflict 2014
HTTP error 69
nosuchsection 8
pagedeleted 1
protectedpage 246
ratelimited 34
rvnosuchsection 7

Sadly 1649 of these users were trying to make their first edit [3]
And most of these problems were on enwiki [4]:

dewiki 5
enwiki 1997
eswiki 1
frwiki 4
jawiki 1
kowiki 4
ptwiki 1
ruwiki 1

Looking closer at the timestamps the majority of enwiki errors (1909
of them) happened between 1am and 3am on Tuesday the 19th November UTC
[5] with 1844 of these occurring between 2.30am and 3am [6]. This
would be around Monday 18th November 5pm-7pm PST. All these edits
happened in stable mode. Does anyone know why might have been
responsible?
