After almost 24 hours of downtime, finally the site is back online. We are there at REACH Datacenter to remove the server at 10pm and after that we reached Qala Datacenter about 11pm. 2 mistakes on our part, firstly we did not bring any CentOS  installation DVD to install on Derrick Server and hence we wasted about 2 hours to download the file via torrent at 500KB/s. Since all of us are using old laptops, it took us about 45 minutes just to burn and verify the DVD. The first DVD that we burnt using Michael laptop, the server has problem reading it. Only at the second attempt using my laptop, it works. Hence we wasted another 1 hour and 30 minutes.
The second and biggest mistake of all is we (Derrick and I) forgot to change our Direct Admin license registered IP, the license is still being tag to our old server and hence DirectAdmin cannot start. By this time it is about 4am and everybody is tired, decided to pack up at 5am and went home, after dropping Derrick at Jurong East interchange Michael and I went to my mom office to collect his monitor that he has left it there. Derrick called me and say that his Direct Admin license IP has been updated and asked me to check mine, and yeap, mine is updated as well. Michael updated the license on our server and it just took 5 minutes. Went for breakfast after that at the canteen below my mom office as it operates 24 hours. After everything was done, it was about 6am. Sent Michael home and reached home about 7am.
The waiting game is for our local shitty and slow ISP to refresh its DNS records to reflect our new server IP. Apparently, Michael told me that Starhub do that every 15 hours while Singtel do that every 30 hours. It is because of the DNS propagation that makes this site goes down for about 24 hours.
But anyway, the site can now be considered running on a “dedicated” server with a guaranteed 1Mbps line with a shared 10Mbps burstable line and the server is hosting about 10 domains only.
