Think I have this resolved. Looks like the new IP has the Content Delivery Network wondering where to look. I've disabled it for now till propagation is complete.
Nathan, who is your CDN provider? Do they use DNS to find your source server(s) or some other (wonky) mechanism?
MaxCDN is the provider. I've not looked into how they work but I was seeing big wait times in page loading coming from them. I shut the CDN off and page load times dropped incredibly. I plan on reaching out to them later today to figure this out.
4 Days out from from the migration and all the little bugs that have been found to date have been squashed. Thanks everyone for letting me of oddities you found. That doesn't mean we've found them all, if you should run across something odd or not working properly please do let me know.
Found a biggie one yesterday thanks to the help of an intrepid M/A member. When adding an image to the Gallery an error would be tossed and the image not uploaded. This has been fixed.
