Hello Adolf,

Thanks for raising this. There seems to be a problem here indeed.

Correct. Since you reported the domain as missing and Stefan accepted the report, I cannot reproduce the problem any more unfortunately.

This is fixed now.

I analysed my algorithm that is actually pulling all domains from the lists and removing anything we don’t want to export. This seems to be working well.

The problem itself seems to be in the dead checker. I have found a couple of more domains that seem to have been removed from the list because the checker assumes that they are dead which they are not. I manually ran the checker again on the affected domains and of course they came back just fine :)

So I am not sure where to go from here. Generally it is a good idea to remove completely dead domains, but what is it worth if this is not 100% accurate.

We could still run the dead check to have a feeling about what our upstream sources are giving us and simply always export everything. That way, we are always on the safe side. The downside is that the lists would at least double in size which means more bandwidth and more memory usage for no reason.
