It’s obviously an Avast server problem with VPS. I have 3 Win 7 laptops running AIS which are still on VPS 150417-0, while my 3 Android devices are on 150418-1. On the laptops, I am getting the streaming updates, currently at 4 folders corresponding to the 150417-0 VPS as well as the VPS that haven’t been served to them yet. Avast sure seems to have a lot of trouble maintaining their servers.
I wonder how many streaming updates Avast can handle before it’s efficiency is compromised. So far, that point hasn’t been reached.
VPS updates are now being served. I turned on my laptop 30 minutes ago and received VPS 150419-0. Streaming update folder 150419-1 was created a few minutes later. Servers are back to normal for now, as they usually are.
