What's wrong with the up2date???

[António Vasconcelos]

Hello.
I have Fedora installed (Core 1) and I just can't complete the update 
list.... Or because of  service was reseted or, because the downloads 
are transfering at very low speed (and it's is not a problem with my 
connection...).
Can anyone tell me what is happening?
Too much people accessing the site, the updates or just....????

Thank you very much to all for your patience and dedication
Best regards
