A few editors on the English Wikipedia have been noticing a problem since around January 15 of "connection timed out" messages, very slow performance, and being logged out. Preview is getting hard to use because so slow, or failing entirely, and some edits are not being saved. Some discussion here -- http://en.wikipedia.org/wiki/Wikipedia:Village_pump_%28technical%29#Slownes… nd_timing_out_error_message Does anyone know whether there's work going on that might be causing it?
