The beatings will continue until morale improves

So over the weekend, Wikimedia Labs ran into a bit of trouble. Database replication broke, and was lagging about two days behind the live databases. But, thanks to tireless efforts by JCrespo, replication has now picked up again, and replication lag should be back to normal soon (even though there might be a few bits missing).

Now, this in itself is not something I would blog about; things break, things get fixed, life goes on. But then, I saw a comment by JCrespo with a preliminary analysis of what happened, and how to avoid it happening again:

“…it is due to the contraints we have for labs in terms of hardware and human resources. In order to prevent this in the future, I would like to discuss enforcing stronger constraints per user/tool.”

So, there are insufficient resources invested into (Tools) Labs. The solution, obviously, is to curtail the use of resources. This train of thought should be familiar to everyone whose country went to a phase of austerity in recent years. Even though, it now seems to be commonly agreed outside the cloudy realm of politicians, that austerity is the wrong way to go. If you have a good thing going, and you require some more resources to keep it that way, you give it more resources. You do not cut away scarce resources even more! This is how you go the way of Greece.

This is how you go the way of the toolserver.
