deb.debian.org is an extra super fancy redirection thingy that uses "SRV" records instead of ordinary round-robin DNS. Most of the time, it works, for most people. But every once in a while, you get redirected to a mirror that's out of date. Unfortunately, when that happens, it's really damned hard to figure out that this is happening, or how to fix it. In fact, the only way I know how to force it to use a different mirror is exactly what I recommended here -- stop using deb.debian.org entirely. You could try going back to it in a week or two, and maybe the mirror it's using for you will be up to date, or you'll get a different mirror. Or, you could stick with your ftp.COUNTRYCODE.debian.org mirror set if it's working well for you. The country code mirror sets aren't immune from staleness issues either. There've been plenty of times when one of them has been out of date, and people have been advised to use a different country code for a while, until the mirrors get fixed. So, just keep an eye out for this kind of problem no matter what mirrors you use.
