For those of us who just joined this forum because (as ClickChick puts it) we awoke in shock, I've been doing a lot of reading on Polisy (pro) and the insteon dongle (insteon portable usb adapter and interface 2448A7).
I know most of us are just looking for the simplest solution to getting back to life as normal, and it looks like the Polisy solution (although it might have its 'steep learning/programing curve') will fill that role and then some.
As the "pros" here alude to, Polisy essentially replaces the Insteon hub (non-cloud based as of yesterday) with a LAN server that will not be reliant on any outside source. Your insteon hub then becomes worthless (RESET or not) unless, as one member wrote, you use it as a strong local node (I haven't explored that yet). Dongle is about $48 on ebay w/tax-shipping; Polisy from UD direct is $379 and the Polisy Pro (only one available currently when I looked last night) is $409. I personally agree with another member and always hardwire (ethernet direct) critical info transfer, so I don't see a need myself for the WiFi/bluetooth Pro option currently (but I also agree with Teken that for only a few bucks more you have the latest and greatest, and who knows how that might be useful next month?)
Polisy will broadcast via RF 915 MHz signal to the dual band insteon devices nearby through the Insteon interface 2448A7 (Insteon dimmer 2477D are dual band; are the 2476D dual band also? is that what the D stands for? Power line only devices won't work as the initial jump point unless you're using the older PLM ("power line modem"?) but this relies on older serial line and has proven very unreliable in the long run; ie stock up on capacitors! There's also a PLM USB plug in modem from Smarthome, never seen it) Best to pay the price for the latest and greatest (Polisy (pro) with a usb adapter/interface.) Once programmed, all your Insteon devices should be up and running, with scenes and voice control.
Better still, this device is built for FULL CONTROL. Not just insteon, but also Z-wave, energy devices, Tesla chargers, etc etc. Not being any sort of expert with all this, I ask ... what other lighting switches could I purchase as I expand, that would rival Insteon Dimmers in form and function??? (just bought 3 dimmers on ebay at a ridiculous price).
Here are the UD links I found that will be helpful getting everything set up.

OK, that's a mouthful. Hopefully its of some help to all the other novices/semi-tech users to getting back to normal.
I haven't purchased the Polisy yet, as I'll be away from home for a bit and figured I'll buy it and set it up on my return. I did buy the insteon adapter/USB interface 2448A7 on ebay last night -- figuring it may be in short supply soon, as has been discussed here extensively. One could speculate that Insteon product 3rd party market (ie eBay) prices may drop soon, as people unload Instegone for other platforms.
