We're planning on doing another master split this weekend. The idea is to
split off the following databases onto their own master:
bgwiki
bgwiktionary
commonswiki
cswiki
dewiki
enwikiquote
enwiktionary
eowiki
fiwiki
idwiki
itwiki
nlwiki
nowiki
plwiki
ptwiki
svwiki
thwiki
trwiki
zhwiki
This is a hand-selected list designed to simultaneously balance both the
data set size and the request rate across the two non-en partitions. Some
of the data used can be found at:

There should be no significant disruption to the main web service. Some
subsidiary services, such as toolserver replication, may be affected.
