Majority of Microsoft Servers last week end up unintentionally self patching and restarted. The cause of that was resolved and majority of critical servers were patched over the weekend as well.
There are still a couple of servers I need to finish patching so will plan to patched and reboot them this Wednesday evening. Note that critical departmental website servers and file servers were all already patched so the remaining are mainly low impact and I anticipate minimal downtime.
If you have any questions please let me know.
