No.
Apparently, for whatever reason, the master database server for enwiki
got overloaded. This was following a few updates, which may have (I
don't think they're sure yet) caused the problem. What actually
happened was the database server had a large number of queries stuck
in the 'statistics' status, leading to overload, leading to wiki down.
Enwiki was set to read only, and the Almighty Tim, Patron Saint of
Master Databases, arrived on the scene to heroically run the
master-database switch script. The S1 (enwiki) master database was
changed from db14 to db16, and db14 was removed from the slave
rotation. From what I understand, db14 will need a swift kick to the
power button to make it all jolly and happy again.
For the latest information when the wiki is down, you can always visit

irc.freenode.net.
