Some very dangerous Windows hacking tools have leaked, our infrastructure doesn’t seems to be at risk but it’s not a bad idea to install the latest Windows updates.
In fact the timing is perfect (details on the vulnerabilities on a Friday evening, before Easter week-end) so we’re updating our servers this Saturday.
More details here and here.

Like always VPS will be unreachable for 10/15 minutes, and will be like suspended/frozen, not rebooted.
Our dear users are more than welcome to install the latest Windows updates ASAP.
