Lightsail also does not offer any form of virtual serial console to access a VM where you've accidentally broken networking or ssh, when even the crappiest lowendbox-tier VM provider generally does. The only way to 'recover' a lightsail VM that's in that state is to export the storage device to full amazon services starting from a $25/mo VM.

everyone uses github because everyone uses github. it's relying strictly on social effect right now.

Well yeah, obviously. I think the point was that uptime is not the only concern, and that a service sufficiently attractive in other ways can get people to overlook a lack of reliability.

Uptime is overrated.
