Dynamic DNS update extremely slow (Cloudflare)

Hi there,

is the DDNS update for Cloudflare records slow for anybody else? From todays logs:

As you can see, it always takes about ~30 minutes to update a hand full of records.

@flobernd I noticed a problem too with cloudflare. DNS-O-Matic complained a lot this night, it was not specific to pfSense.

Yes, tonight there was a complete Cloudflare API outage it seems and the DNS records didn't get updated at all (some timeouts logged). That was the reason I digged into that problem.

As of right now, updates are succeeding, but they are super slow.

Do you think this is as well a temporary issue? Not sure if it was much faster in the past.

Tonight it again took ~35 minutes to update all 5 DNS records 7 minutes per record seems way too long for a simple API call against Cloudflare.

I suspect there is something else going on. Will try with verbose logging next time and see I can spot something interesting.

@flobernd I just did a test but not with pfSense and it was normal, so no problem on CFs side.
