The English-language Wikipedia will be in _read-only mode_ for a few hours tonight (Feb 9->Feb 10) while the database structure is altered to eliminate some of the remaining performance drags before the heavy weekday traffic gets into full swing.
This will also fix the out-of-order page history bug, which was caused by a temporary workaround to the slow history problem.
The downtime window will cover roughly 04:00-08:00 UTC (UK time). For us USians, that's 8pm-midnight PST / 11pm-3am EST. Australians & others, please check http://www.wikipedia.org/wiki/Time_zone for the appropriate offset to your local time. (I'm not certain of the end time; it may run shorter, and hopefully won't run longer. It's a big database, and mass modifications take a *long* time.)
Will run a while longer; my initial estimate left out doing a backup run first, which itself is rather slow. My apologies...
