please put c3sl back!

[Carlos Carvalho]

Hello

We are ubuntu.c3sl.ufpr.br. We're currently not enabled for download but we
should. We had a problem on Monday that lasted about 3h and during this period
the verifier excluded us. However, it should have put us back but didn't. We
hav been back to normal operation and up-to-date for 4 days already.

Note also that we're official country mirror (to use the Debian language) for
most of South America, so you should put us back in your dns for
