We have been updating all machines to ensure we are not vulnerable to attacks such as SPECTRE and MELTDOWN (More information here: https://meltdownattack.com/). Much of this requires the system to be rebooted to fully apply the changes and the mitigations of the system kernel.
During a routine reboot, which normally take up to 5 minutes at most for the system to recover back to useful, the system decided to perform a disk check (which happens every X number of reboots), and thus made this process take a bit longer than usual.
I am happy to say that we are no longer vulnerable to these exploits.
We do apologize for the inconvenience. If you are still experiencing any issues with your site or email, or if you have any questions. please get in touch with our team - https://help.justhosting.com/
