Wonder if they are dropping the PPP to force us to connect back up to the other gateway, and are moving people across one by one? Although you'd think they'd check first or do it out of hours, so maybe it was something else that caused your disconnection and we are getting the other gateway on the next PPP session?
When I finish work I will drop the PPP and reconnect and see if I get the other gateway as well.
Edit, have the answer, they are disconnecting us and so forcing a new PPP, it has just happen to me now and my gateway is 18.104.22.168. I suspect your Edgerouter didn't take kindly to the drop and so didn't restart PPP, but on pfSense it was pretty seamless.
