Weird shit with DNS question - GoFuckYourself.com

I switched the DNS for a domain to a new server over 80 hrs a go
And I just don?t get this

I have two connections through different ISP
One resolved to the new server two days ago but decided to go back to the old server tonight WTF?
The second ISP is still stuck on the old server IP

Anyone seen this crazy shit before?

DNS cache from other ISP has not been updated yet; it should be soon... try loading the url in your browser from that connection, usually forces the update within 24 hours but these things take time...

Good luck with your site

If you're seeing the DNS go to the new IP then revert to the old one it's possible that one of your DNS servers doesn't have the new information on it. What's the domain?

Next time you do it, the best way to prepare for a server switch is to back off the Time To Live (TTL) value of your DNS records. This value controls how long the record is cached for - normally it's something like 24 hours, but if you set it to 2 minutes a couple of days prior to the move then you will get 95%+ of the surfers accessing the new server within 2 minutes of the DNS change.
