Status 429 - rateLimited

[futureweb]

Hey there,
we had to renew thousands of Certs when CAA Rechecking Bug happened.
Starting with today we get some 429 Errors:

429
{
  "type": "urn:ietf:params:acme:error:rateLimited",
  "detail": "Error creating new order :: too many currently pending authorizations: see https://letsencrypt.org/docs/rate-limits/",
  "status": 429
}

Domains:

• www.kitzbow.com
• www.sonnenhof-going.at
• www.zwoelferblick.at
• and others

We haven’t had such Errors for years … no changes on our side. Any idea on that?

thx, bye from Austria
