A major template was modified today, this caused almost every page to need to be thrown away from the cache. This has the side-effect of making our slave-database (which is a copy of the main database) get way behind where it is supposed to be since there is a bunch of other work for the server to do. This means that edits you make today might take a little while before they show up.
Currently, the slave is falling further and further behind. It’ll probably continue to get worse before it gets better, but hopefully we should be okay in a day or two.
Sorry for the inconvenience!
