Why do you do this on every request? Why not have a cron job retrieve an
update every 20 minutes or whatnot and stuff it into a database table
for your page to access? Then if the cron fails to retrieve the feed it
can just leave the table as is, and your visitors can happily view
slightly outdated feeds? Additionally this will be so much faster that
your users might even hang around on your site :)
Cheers,
