We are confused why you keep saying the agents are not reporting outages, all three have done just that.

As can be seen, outages are being logged. There was a problem with notifications which we fixed as soon as you told us about it.
Did you read the links that were sent? Outages are being recorded but most of your problems are not IP outages, they are some other kind of disconnection.

The technology is the same in terms of how the agent works but the binaries are of course different since they run on different platforms.
cannot identify an outage
See images above.
are monitoring inactives
Because that is where most of the problems you are experiencing are, disconnections, not IP outages.

Yes, there would be minor differences in timing which is expected since loops have to run so timing can be a bit different.
So next question is: is it possible, without any specific >detail, understand if all three agents are connected the >same way within the LAN (different VLANs, directly >connected to the router or thru a switch, different rules >in the firewall)
Sorry, I'm not seeing the actual question. Can you elaborate on this please.

An image of what? From whom? For what?
We've spent two days solid on this and still willing to help but cannot know anything beyond what you are explaining without remote access. Even with remote access, it might not be clear what's going on but we're still trying to help. Just kind of blindfolded at our end other than what we see from your agents.
What we see is that there is something on your network that seems to be blocking communications here and there. It seems to be random, like maybe a firewall rule suddenly kicking in after it's seen a certain amount of traffic to/from our network.
If this were a common problem, we would see it across all of our agents but we don't. We only see it in your reports and it's as odd to us as it is to you.
Remember that this service is not the ultimate answer to everything, it is just another tool. It automates as much as possible logging disconnections and IP outages. It is meant to monitor your ISP, not your LAN. It is not a network diagnostic tool, it is part of your other tools that you would use to find and solve IP problems.
Other than monitoring to see if we can catch a clue, we so far have not seen anything that tells us what is going on but we are also blind since we cannot see what's going on from the agents point of view.
