Has anyone else been getting a lot more errors on sh.itjust.works recently? Could the server be overloaded?

I've been getting a lot of these messages lately:

SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data"

So I decided to look at the network requests in the browser console. After all, what JSON data was it trying and failing to parse?

Well, turns out that it was pretty much always:

Timeout occurred while waiting for a slot to become available

I don't do a lot of backend work, but I suspect that the lack of slots might be referring to the server running out of resources to process all of the ongoing user activity concurrently. Could we be running into scaling issues?
