You’ll also want to be sure your ACME client is running frequently - both for the sake of renewing short-lived certificates and so as to take advantage of ACME Renewal Information (ARI). ARI allows Let’s Encrypt to notify your client if it should renew early for some reason. ARI checks should happen at least once per day, and short-lived certificates should be renewed every two to three days, so we recommend having your client run at least once per day.

| emily | wonder if we should consider moving to 2×/day | 16:04:52 |

 m1cr0man | I mean we only ever had it > 1 day for LE's sake (DDOS) 😅 I don't see why we couldn't do 2x/day.
Sorry just catching up on this all now. Was on holidays. | 00:26:31 |
| hexa | ideally we could configure the intervals relative to the total certificate lifetime | 14:50:52 |
| hexa | * ideally we could configure the intervals relative to the total certificate lifetime provided by the profile | 14:51:01 |
| hexa | but in the end it probably doesn't matter too much | 14:51:41 |
| hexa | I still worry a bit about shortlived certs and CT logs | 14:52:13 |

 Arian | As in. CT log performance? | 14:52:44 |
| hexa | * I still worry a bit about shortlived certs and the impact on CT logs | 14:52:46 |
| hexa | yeah, they are these very big and slow platforms already | 14:52:54 |
| hexa | and now we effectively allow people to recreate their certificates 15 times as much | 14:53:19 |

| emily | the sunlight effort is making ct scale much better | 14:54:48 |
