Singapore Ubuntu Mirror Always Failed on Weekend

I'm not sure everyone facing this issue or not. When I update or install something on my Ubuntu 14.04 server, it always uses "sg.archive.ubuntu.com" Singapore mirror and it's working during weekdays and failed on weekend Sat and Sun. So I make changes on the apt repository.

$sudo vim /etc/apt/source.list

comment out # deb http://sg.archive.ubuntu.com/xxxx

and add deb http://au.archive.ubuntu.com/xxx

then run the command apt-get update then solve the issue.
