As much as I appreciate what they offer at no cost, I have experienced more downtime from their service then I would like. My Uptime Kuma dashboard reports a 99.98% 30-day uptime from their service (mainly small 1-2min down-times every couple of weeks), but I have experienced at least one 7ish hour period a few months back where no duckDNS queries were resolving for any domains I checked. And I never found any official source giving a reason or even acknowledging this this outage. Again, free service, I do appreciate what they offer.

They probably don't want to have the extra headache of having made a promise of uptime in anyway, if anyone uses a free service for stuff that can't go down the fault is on them

Yeah I've noticed that too. I have a systemd service that periodically updates a DNS record on duckdns.org and it fails quite often.
