I have recently cancelled my subscription with them. I have learnt that their setup is not HA (because their outage took my internet with it for a bit) and you can't make it HA either, you get assigned to 1 endpoint and if that's down your DNS is gone, even when they have loads of other working endpoints around you (and their suggestion to this is to add a different DNS as a fallback). Frustrating, as I did like their service for the price.
Kind of even more annoying was that while I was their customer I couldn't get through their AI support bot to a person to just raise this as a problem and get a proper response, but as soon as I cancelled an actual human reached out to ask why.
