DNS Propagation - 7:17 pm
uh, my windows is caching the DNS records too!
Computing , Internet , Site Issue , Web Hosting  -  poster 

Rawwwrrrrrrrr ~~~~~~~ !! This site is finally up and running again claphand2

beh tong nia... I can't believe my lame ISP really took 72hrs to update their cache for DNS records ! Last week, my webhosting company actually planned to do some RAM upgrades for the server. Then in the middle, I'm sort of confused, but I think they moved some of the accounts to another new server/datacenter in US. So new server means new IP address. That also means http://ahkuan.com is pointing to another new IP address. The changes is made effective pretty quick in the top registration database and the webhosting's DNS servers, however, the so called DNS propagation process is causing all the mess around.

Let's go in plain english... You see, every ISP cache the master DNS records and read them locally instead of looking them up on the Internet each time someone wants to view a website. Some ISP fetch a new copy once every 24 hrs. However, some ISP (like the one that I'm using) they fetch a new copy once every 72 hrs... or even longer ! So even though the domain name ahkuan.com is already mapped to a new IP address in the top level domain servers, but your ISP's DNS cache is still pointing to the old IP address ! So there will be chaos... some will be viewing the most updated content on the new server but some will still be visiting the old content on old server. Unless everybody is using pure IP address xxx.xxx.xxx.xxx instead of ahkuan.com, you'll probably have to wait up to 72hrs until your ISP refresh their DNS records cache.

It won't be surprised if you're still having problem to resolve to the correct address even after your ISP updated the cache. The problem might be your operating system is caching its own copy of DNS records. For windows user, go to command prompt, and type the following command:

ipconfig /flushdns

This will flushes and resets the contents of the DNS client resolver cache. Try /displaydns to display the cache content.

Site affected during DNS propagation - 8:02 pm
Site Issue , Site Updates  -  poster 

Just blog this to keeptrack the update history on my site.

Alright, my webhosting company has moved my site to another new server. During the DNS propagation period, some people are visiting the latest content on new server and some are seeing the old content on old server, that causes some of the shout messages and also my weblog entries are messed up in new and old server. Luckily I still got the chance to do a database dump on the old server and merge with the dump on new server. The rest of the files (eg photos) can be uploaded again from local computer. So now everything is restored and should be appeared correctly in order.

ps: It would really freaks me out if I can't perform database dump on the old server because I don't have any recent backup... So regular backup of your database is really a good habit... (nah, I'm a lazy person.. who cares anyway about database backup eh ?)
