Same, considering switching after this for sure.
Looks like it came back up after about 4(?) hours. I noticed there was a "special offer" to extend my subscription for about half the price. I think what I want is to pay more for something that looks vaguely like an SLA. Or maybe even a description of how they have two data centers and their fail-over process is tested frequently.
Lumo, which could have been a great offering, similarly breaks after every fifth message or so and is substantially behind SOTA offerings. IMHO Proton has jumped the shark and this is just the final straw.
