Ohh it was a renewal for “co.undo.it”, I did not notice that, thanks for that info!
Also, thanks for the URL and the time when I can issue a certificate again, that really helps!
Also I got ownership of this subdomain on 20th September, so rate limit window didn’t open since then (and it’ll now open on 2018-09-26T03:31:48.000Z)
I’ll set up a bot to automatically issue a certificate at that specific time because I’m mostly unavailable due to work.
Once again, thanks!
