Old DNS records
I'm having an odd issue, which I believe is DNS-related.
I used to have two of my domains hosted on a DSL connection of one of my friends. Anyway, he's being shipped off to Iraq and his server has been unstable as of late. So, I moved my hosting to hostdepartment.com, and updated the DNS servers listed with my registrar. However, it seems like some servers, including the email reply notifications from linuxquestions.org, are not seeing the new server. I updated the registrar about 3+ days ago.
By the way, my two domains are webgroup.org and cosmicsys.com and both should resolve to 18.104.22.168.
Anyone have any thoughts or experience with this? I'm guessing that the old server still having a different DNS record is somehow causing problems, though nobody should be going to it for records, I thought.
