Hi,
As there are 3 or 4 versions, the automatic VPS updates don’t seem to take place at startup and after the set time (120mn), I have to force them in manu to take place.
Of course, I’m still protected by stream updates, but they end up accumulating abnormally.
So far, there have been 17 in the last 3 days.
What’s more, I’m getting a link back in the DNS cache to “ping.avast.com.akamaized. net”, just like the last time the updates weren’t happening, so I think the 2 are linked. 
edit:just after my post, it updated automatically
