pear.php.net is down. How to install mirror?

I was trying to install new packages in my PHP environment development via PEAR but as shown below:

File http://pear.php.net:80/rest/p/packages.xml not valid (received: HTTP/1.1 404 Not Found)

it seems that php.net is down.

I tried to setup a mirror since us.php.net which Digg hosts with the following command:

pear config-set preferred_mirror us.pear.php.net

which gives the following error:

Channel Mirror "us.pear.php.net" does not exist in your registry for channel "pear.php.net".

Attempt to run "pear channel-update pear.php.net" if you believe this mirror should exist as you may have outdated channel information.

Of course I can't update the channel since php.net is down.

Does anyone know how i should proceed?
