Site offline?

I upgraded my daughter's desktop to squeeze, and the last step was to install Trinity. Unfortunately, the trinitydesktop.org site is not found in iceweasel, and when I tried to download the key for the repository, I get: # apt-key adv --keyserver keyserver.quickbuild.pearsoncomputing.net--recv-keys 2B8638D0 Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /etc/apt/secring.gpg --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver keyserver.quickbuild.pearsoncomputing.net --recv-keys 2B8638D0 gpg: requesting key 2B8638D0 from hkp server keyserver.quickbuild.pearsoncomputing.net gpgkeys: HTTP fetch error 7: couldn't connect to host gpg: no valid OpenPGP data found. gpg: Total number processed: 0 Is there a problem on the site or is it local network problem? Thanks, --b
