mirrorservice.org - squeeze-updates "Release file expired"

[Gavin Westwood <deb-mirrors@solutium.co.uk>]

The Debian squeeze-updates mirror at mirrorservice.org appears to be out
of date.  I get the following error from aptitude when downloading updates:

"E: Release file expired, ignoring
ftp://www.mirrorservice.org/sites/ftp.debian.org/debian/dists/squeeze-updates/Release
(invalid since 19d 13h 11min 18s)"

Thanks

Gavin
