The Labs team has spent a lot of time discussing how to avoid future
capacity crunches. This will be a long term consideration involving
coordination with project admins.
Outline of our progress:
- Self-service instance creation is again enabled for Labs in Horizon
(https://horizon.wikimedia.org) <https://horizon.wikimedia.org%29>
- We've reduced the permitted overcommit ratios for RAM and disk space
(T140119 and T140122)
- We've reduced default quotas which affects new and some existing
projects. We believe this will have two advantages: 1) When growth
happens we'll know about it, and 2) There will be an opportunity to
consult about what growth is necessary and how best to take advantage of
capacity.
- We are transitioning to a process for quota increase requests using
Phabricator (see T140904)
- Even with our new nodes we are still tight on space without diligent
clean up. https://wikitech.wikimedia.org/wiki/Purge_2016
Let me know if you have any questions or concerns!

We're running into serious capacity issues this week, so I have
temporarily disabled the creation of new labs instances. We have new
hardware sitting in the datacenter already, so at worst we'll be back
to normal sometime next week.
Sorry for the inconvenience. And, as usual, if you have instances you
aren't using, please delete them!
