repository packages not found

I successfully updated my Ubuntu 8.04 lts server Hardy many times, but today when I:

sudo apt-get updateI got errors like:

Err http://ro.archive.ubuntu.com hardy/main Packages
404 Not Found
Should I worry about this?

might be the 'ro' server down, open synaptic to use 'main' server instead, then update
