A few minutes ago (around 19:50 UTC, on 26 June 2019), the main pages of SE websites said there was a server maintenance, giving two links, one to twitter @StackStatus and the other to Stack Exchange Network Status. (I tried to retrieve the URL of the maintenance page from my browser history, but it shows no more than "https://stackoverflow.com/")
Apparently, the latter is not actively maintained. The newest post is from eleven months ago (11 July 2018). What is the current status of that site?
I suppose keeping a link to an abandoned meta-website is kind of a bug. If the site is officially abandoned in favor of the Twitter account, why not remove the link to that site from the maintenance page?
