    Either our industries standard canary in a coalmine or Microsoft's volunteer army of uncompensated QA and tech support depending on who you ask.

    Remember, listen to others wails of pain before adding your own, and silence doth not equal success, for Redmond may have broken the TCP stack again, and the screams may have to wait till someone can hack together a working internet connection.

      Shirley MS should be rolling out these patches across their entire company a day or two before everyone else gets them. If they are good, fine, if not, well, eat your own dogshit MS and stop feeding it to us for testing.

    Cue the black helicopters

    They've almost succeeded with getting rid of on-prem Exchange with their diligent work on b0rked CUs in the last several years. Since November last year, they seem to be getting into high gear with stealth-deprecating Active Directory too.

      Of course you need to move on Azure Active Directory, everything on-prem now is frowned upon....

    Greater risk?

    Patching on Patch Bluesday, and waiting to approve the updates on WSUS for a week to 10 days as not to get burned by a simple update? Or get pwnd by a gaping hole they're finally trying to fix?

    Paris doesn't know either...
