Funding is running out for the largest member of mybinder.org, which has been sponsored by the Google Open Source Program Office. gke.mybinder.org will shut down and there will be a reduction in capacity at the end of April, 2023 (end of this week).

Key points:

• Our funds on gke.mybinder.org, the biggest part of the federation, will run out in April. Google has decided not to provide more credits.
• Traffic previously sent to GKE will mostly be delivered to OVHcloud, which has less capacity. We are also working to deploy new federation members to spread the load.

Service reductions to expect:

• This may come with an increase in errors and failures, as GKE has been the largest and most stable federation member
• We are currently looking at reducing the total capacity of Binder by 60%, so you may get rate limit or capacity errors
• We will start more aggressively deleting older cached builds, as storage costs have increased.

We are still working out the details of the shutdown and deploying new federation members, but mybinder.org users should expect disruption to the mybinder.org service and to see an increase in messages that the service is at capacity in the short term.

The plan:

• Thursday: gke.mybinder.org will be removed from the federation (user sessions not disrupted, but no new sessions will start there)
• Friday: gke.mybinder.org will be shutdown, and mybinder.org migrated to a smaller cluster

You can help us keep mybinder.org running by donating to Binder or encouraging your organization to join the BinderHub Federation.

We are grateful to the Google Open Source Program for their funding thus far.
