I work at Let's Encrypt, which Cloudron uses to issue certificates per its documentation. We've identified that Cloudron disproportionately sends traffic at midnight and noon UTC. I suspect this is the automated renewal noted in Cloudron's documentation.
Let's Encrypt receives disproportionately high amounts of traffic at midnight UTC in particular, as well as the top of other hours. I'm attempting to find software which hardcodes these times to ask the developers to have them renew at a random time of day.
Would it be possible to have cloudron renew at a random time of day? If so, is there an update mechanism that would allow existing clients to install this fix?
Thank you in advance,
