don’t really know what the problem is.
Pretty irritated at the fact that DreamHost doesn’t handle changes to a subdomain’s A-Record very well. Supposively, the new A-Record you submit for a subdomain will overwrite the default DreamHost record. Not so; it just seems to bounce back and forth between the two and mostly lands on the default. It could be that the DNS hasn’t fully propegated yet, but I doubt it - it’s been over 72 hours from what I can figure.
I’ll be talking to them soon if I actually wind up doing something substantial with this. Just… very, very annoyed. Until then, I’ve disabled my tumblr’s custom domain feature.
