Currently, the kbin.social instance has planned maintenance. They are busy upgrading the infrastructure to Kubernetes, using Docker containers. They said it shouldn't take much longer than 1 hour downtime in total (if everything goes fine).
The migration will help to dynamically scale the instance, to remove the growing pains. And hopefully increase the availability (uptime) as well.
Soon additional setup configurations, best server practices and ansible playbooks will be shared with the community.
In the meanwhile you can of course use other instances (I bet you are reading this message right now from another instance).
Yeah I just tried to log in at Kbin (hooray for accounts on multiple instances!) and saw that it is expected to be back up by 20:00 UTC? But...it's currently 20:11 UTC so I'm guessing it's taking a little longer than expected.
I was afraid of this... I already told Ernest to list multiple instances on the page, so people can visit other instances. But it seems to be down for maintenance a second time.
