Nearly all page requests on Wikivoyage are currently failing with "Fatal exception of type MWException". See for example https://en.wikivoyage.org/wiki/Special:RecentChanges. This has been ongoing for at least 10-15 minutes.
Ditto at Wikimedia Commons: "[8672d3f8] 2014-01-02 18:54:37: Fatal exception of type MWException". Was reported at [[Wikipedia:Village pump (technical)]] at 18:40.
To clarify, I got the error above accessing the Main Page on Commons. The Main Page on Wikivoyage works for me, but Special:RecentChanges is broken on both sites. The API still works fine; it's just normal web access that is broken. Looking at recent changes on Commons via the API (https://commons.wikimedia.org/w/api.php?action=query&generator=recentchanges&prop=info|revisions&rvprop=user|comment), I see some normal users (i.e. not bots) are successfully making edits, including some IP address users. In case this is a geographic thing, I'll note I'm trying to access Commons from the UK.
I've found that reloading a page enough times on Wikivoyage will eventually result in the page loading correctly, but even the main page is usually failing.
Both Commons and Wikivoyage are now working for me. I reloaded the page half a dozen times on each, but no more errors. I've been away for the last hour, but comments at [[Wikipedia:Village pump (technical)#Commons down]] seem to indicate the issue cleared up a few minutes after my previous comment.
https://en.wikivoyage.org/wiki/Wikivoyage:Travellers%27_pub#Fatal_exception_of_type_MWException seems to indicate that this was a localization caching issue that has now been resolved. Wikivoyage seems to be back to normal now.
Thanks for reporting this. https://wikitech.wikimedia.org/wiki/Server_Admin_Log mentions January 2 19:25 Reedy: stuff has been broken and Reedy and greg-g (on Freenode IRC) are aware of it and investigating.
This should hopefully be fixed now: <Reedy> exception.log is also quiet again (to confirm it's fixed) See https://ganglia.wikimedia.org/latest/graph.php?r=day&z=xlarge&title=MediaWiki+errors&vl=errors+%2F+sec&x=0.5&n=&hreg[]=vanadium.eqiad.wmnet&mreg[]=fatal|exception>ype=stack&glegend=show&aggregate=1&embed=1 Closing soon if there's no new issues.
This has been fixed ages ago (around 19:29 UTC).
