Hello. Something weird started yesterday. I heavily use the global watchlist, and open links in many wikis a couple of times every day. Something that never happened before, and happens dozens of times now, in about 90% of the cases. If I work with wiki X and open some page on wiki Y, I find myself logged out there. I can go back to X and press F5, and still be logged in in X, which is the weird part, because I should be logged out everywhere simultaneously from any reason. The only thing that helps for Y is clicking Log in, then the page makes autorefresh to logged in state. Some more people complained about this. I would create a Phabricator ticket, but I have no idea how to reproduce this.
Phabricator is the best place for discussing ongoing bugs or breakages, even if they aren't easily reproducible. Just summarize what you know about it. Thanks!
