I don't know everyone who is involved in maintaining MetaCPAN and I don't know all the details of the performance related issues that have been an ongoing challenge (I believe they have been related to relentless bots?).
In any case, this last week MetaCPAN seems to have been running flawlessly!
So rather than burying a thanks note in a github issue, I wanted to put a public thanks here to all the volunteers and sponsors that keep MetaCPAN (and CPAN) running.
