RDAP shows a clear domain status, so it looks like this may have been resolved. Only Admin has access to the registrar account, so I will keep this pinned and open until there is confirmation
I opened this topic as soon as my monitoring detected the domain was down. I immediately contacted the registrar and they were able to resolve it quickly and without further hassle.
The downtime I detected on my end was roughly 1.5 hours, but DNS caching means different results for different people.
