Suggestion in the event Cloudflare API is partially down

[nodevx2]

Just a suggestion in the event that the Cloudflare API is down because this happened to me multiple times in the past.
There should be a protection in the script to prevent deletion of Lists and Rule on Cloudflare if the API is partially down such as if the API is up for deleting lists and rule but unable to write/upload the new list due to a problem on Cloudflare side.
My suggestion to prevent such issue is to make a test by creating a small list(jus a few domains) and a rule using different names to Cloudflare API prior to running a deletion of all CGPS lists. If such test succeed, delete the test list and rule and proceed in deleting the target CGPS lists and rule. If the test fail to create the list and rule, that indicate a possible problem on Cloudflare side so do not proceed in deleting the list because it will leave the DNS without a blocklist.

PS: I'm not an expert in coding so I'm not sure if my suggestion is the best way to prevent such issue.

Would editing the existing list(s) and rule remove your concerns?
This way you're never unprotected. At worst a partial update would mean you're not "up to date" but a re-run once the APIs are available again would complete the process.
e.g. #144
