Another shot in the dark:
I don't know how you scored an Arris modem with static IPs (I have the
annoying AT&T/2Wire HGV3801 for my statics) but I found that heavy
traffic filled the very small memory for the CONNTRACK connection
tracking table which would cause massive packet loss. In the HGV, a

Yes. Replaced the cables. Changed the ports on the switch..
Only thing I haven't tried yet is replacing the network card.

Derek,
Did you try replacing the cable? Low hanging fruit...

Well, if I unplug or otherwise disable the VM server then the problem
goes away. Similarly, if I shutdown two of the VMs (the two that

Yep, you covered it. Wireshark does whatever tcpdump does, but

probably not worth pursuing. The tcp protocol measures Round Trip

I agree that the problem developing at midnight is too much of a
coincidence. If there are logs, I would try to read them in
GMT/UTC+/-. A /29 octal would be 6 unique IPv4 static IP addresses,
correct? So is there a host with a firewall on one of them? If that
were a bsd system, something like:

I'm not 100% sure it was at midnight; I was basing that on my memory of an
MRTG weekly graph which is no
Derek,
Is it possible to read event logs and determine that some pieces of
equipment are definitely not causing the problem?

So AT&T's network equipment works when nothing is connected to it?
Clearly this is a success story. If the tech had been allowed to try
the new modem, that would have greatly sped up the troubleshooting
process. If it had worked as before, then problem solved. If not,
then you could debug your n

Derek,
Sorry to hear that, and its frustrating. Perhaps AT&T could, in the
meantime, install a different modem temporarily to see if that solves
the problem? I've been through this with various T line providers,
and their default response is often "Something you did", even when the

That might be difficult, as it may be a loose connector or even corrosion
inside a cable or connector or component in a power supply or ???
Good luck.

Hi,
Just a quick follow-up.
AT&T did come, and with their help we debugged the network only to
discover that it's something inside my network that is causing their
modem to go all futzy.
I'm now in the process of trying to debug further, but it's going to
take time. Expect further interuptions
Hi,
tl;dr: AT&T is coming to fix some network issues tomorrow, Sunday,

As some of you may have noticed, there have been some network issues to
