Up until recently, I've been using ftp1.sourceforge.net/debian in my sources.list to fetch my Debian updates, but recently, that mirror, and all the other Sourceforge mirrors stopped working. That's a shame, because I've found Sourceforge's mirrors to be fast and reliable. Are Sourceforge's Debian mirrors down for good?
Since then, I've switched to ftp.us.debian.org, but frequently during dselect or apt-get upgrades, I get lots of 404 errors, even though I do an apt-get update to make sure I have an updated set of package lists. Apparently ftp.us.debian.org is not in total sync with the source. So what's with all the Debian mirror brain damage these days? And are there any mirrors out there left that work?
