Work in progress! EDIT: finished!
We have been preparing for some weeks to upgrade our database architecture to make it more resilient, and yesterday an electrical failure at our hosting provider proved again that it was necessary.
So today we'll be making the necessary changes, with some downtime, but that's to make the service better in the long run!
New table creation will be locked starting at 8AM CEST. You can follow up on our progress on Twitter.
