There is no set schedule for updates, when you first connect to the internet shortly afterwards the auto update function will check for updates if one is available it will either be automatically downloaded and installed or you will be informed that one is available, depending on your settings. If you remain connected it will be checked every four hours.
On average there are 4 VPS updates per week, more in periods of increased activity. I have had as many as 4 updates in a day, so you should have little concern. You can also check what the latest VPS update is at avast! VPS Updates History. You can also initiate a manual update at any time, which will either download the latest update or confirm that your VPS is up to date.
Why are you concerned ?
