Terraform keeps a cache of state files in the
.terraform directory stored in Terraform Cloud so that it can be accessed by everyone in the organization. For existing resources Terraform has to import the state for a defined resource otherwise it will fail. Sometimes the state is invalid or an API will return an unexpected code and Terraform will fail to proceed.
The example below passed the error from the Cloudflare API via Terraform Cloud to the user but does not indicate the error. After verifying the state manually some resource records were already removed from the zone and triggered an
81044 error. But the state was not removed and Terraform Cloud could not find the resource record to remove from the state database.

With the creation of RFC 4408 also new a record type 99 for DNS was created to identify SPF Resource Records. It was advised to have both TXT and SPF records in DNS with the same content. RFC 4408 was obsoleted by RFC 7208 in 2014 with paragraph 3.1 stating the following:
SPF records MUST be published as a DNS TXT (type 16) Resource Record (RR) [RFC1035] only. The character content of the record is encoded as [US-ASCII]. Use of alternative DNS RR types was supported in SPF’s experimental phase but has been discontinued.
