Problems trying to update with Pacman

Question

So I installed Arch Linux for the first time and its awesome. I updated Pacman and after googling I learned that you have to uncomment some servers from the mirror list. I did it and the problem was solved. Yesterday was working but today is not working. Here is the output from pacman -Syy:
:: Synchronizing package databases...
error: failed retrieving file 'core.db.tar.gz' from archlinux.c3sl.ufpr.br : No address record
error: failed to update core (No address record)
error: failed retrieving file 'extra.db.tar.gz' from archlinux.c3sl.ufpr.br : No address record
error: failed to update extra (No address record)

I can't update the core and extra packages but kdemod is updating. That's weird. Here is my /etc/pacman.conf
# /etc/pacman.conf
# See the pacman.conf(5) manpage for option and repository directives
# GENERAL OPTIONS
[options]

# If you wish to use different paths, uncomment and update the paths.

#LogFile = /var/log/pacman.log
HoldPkg = pacman glibc
# If upgrades are available for these packages they will be asked for first

#XferCommand = /usr/bin/wget --passive-ftp -c -O %o %u

# REPOSITORIES
# - can be defined here or included from another file
# - pacman will search repositories in the order defined here
# - local/custom mirrors can be added here or in separate files
# - repositories listed first will take precedence when packages
# have identical names, regardless of version number
# - URLs will have $repo replaced by the name of the current repo
# Repository entries are of the format:
# [repo-name]
# Server = ServerName
# Include = IncludePath
# The header [repo-name] is crucial - it must be present and
# uncommented to enable the repo.
# Testing is disabled by default. To enable, uncomment the following
# two lines. You can add preferred servers immediately after the header,
# and they will be used before the default mirrors.

All Servers from /etc/pacman.d/mirrorlist are uncommented.

Following the wrong instructions maybe?
The Beginners guide, if that's what you followed to install had you going in the right direction.
The only mirrors that needed to be uncommented were the ones in your country.
There is also a package you could install that would rate the mirrors for you and keep the fastest six in a file to access automatically.
I don't recognize the address you have for core, but that doesn't mean it isn't a legit addy either.
I also don't see extra or the community repo in your pacman.conf.
No clue what you have done so no real clue how to fix it.
For instance:
I updated Pacman and after googling I learned that you have to uncomment some servers from the mirror list. I did it and the problem was solved.
What problem?
If you were able to update pacman, something was working.
Everything was working before the update and after the update.
Pelos seus mirrors vejo que tá no Brasil
Os mirrors da ufpr às vezes dão pau.... comente-os e use os da unicamp quando isso ocorrer...
Code:
[core]
# Add your preferred servers here, they will be used first
#Server = http://archlinux.c3sl.ufpr.br/$repo/os/x86_64
#Server = ftp://archlinux.c3sl.ufpr.br/archlinux/$repo/os/x86_64
Server = ftp://ftp.las.ic.unicamp.br/pub/archlin … /os/x86_64
Include = /etc/pacman.d/mirrorlist
[extra]
# Add your preferred servers here, they will be used first
#Server = http://archlinux.c3sl.ufpr.br/$repo/os/x86_64
#Server = ftp://archlinux.c3sl.ufpr.br/archlinux/$repo/os/x86_64
Server = ftp://ftp.las.ic.unicamp.br/pub/archlin … /os/x86_64
Include = /etc/pacman.d/mirrorlist
[community]
# Add your preferred servers here, they will be used first
#Server = http://archlinux.c3sl.ufpr.br/$repo/os/x86_64
#Server = ftp://archlinux.c3sl.ufpr.br/archlinux/$repo/os/x86_64
Server = ftp://ftp.las.ic.unicamp.br/pub/archlin … /os/x86_64
Include = /etc/pacman.d/mirrorlist
O meu já ta comentado por causa disso, nos últimos dias ( hoje?) eles não tavam funcionando...
EDIT: é claro, utilize o repositório da sua arquitetura.... ( copie-os do /etc/pacman.d/mirrorlist )
Thanks a lot. I don't know portuguese but I speak spanish so I can understand portuguese a little. Problem solved.
