OBi100 / OBi110 dying en masse?

I have a small collection of OBi100 and OBi110s deployed around the department as ATAs for our PBX. Oddly, almost half of them have died in the last 7 days, and more continue to drop each day. The dead units still present a dial tone, but cannot dial out and cannot be pinged externally. Most have static IPs and a few DHCP. All are running the last firmware (2886), I'm pretty sure. If I power cycle them, they will come back up but then die again within a few minutes to a few hours. None of the units are using the OBi portal -- they are all "unmanaged" and only configured locally.

I know that these are old units and no longer supported, but I find it hard to believe that these units are just dying coincidentally. They are in different buildings and on different subnets. All are on surge protectors, and some of the buildings have different electrical utility providers anyway, so I don't think it's a big power surge that somehow damaged them. I have thought of bad capacitors too, but still seems like the timing is too tight for that. I've also tried different power adapters from new units, and that doesn't help, so I don't think it's the adapter.

That leaves me with the rather conspiratorial idea that somehow they are programmed to self destruct around this point in time??? Thoughts?

I replaced my personal 110 with a 200 about 6 months ago not because it died, but rather to get the new features and improved operation in certain cases of the 200. That said, I still have a 100 and a 110 that I support and that are used every day. Your situation is odd, though.

What does a traceroute show? Can you get to the device at all, to the router just in front of it?
