gem install failure: is https://s3.amazonaws.com/ down?

I have a problem with gem install command. Until now, everything worked
smoothly. I was able to install or uninstall gems. For example I installed
rails, rspec, factory-girl,....., and many other gems. But today when I
was trying to install capistrano gem I ran into the following problem:
bayram@bayram-R530-R730:~$ sudo gem install capistrano [sudo] password for
bayram: ERROR: Could not find a valid gem 'capistrano' (>= 0), here is
why: Unable to download data from https://rubygems.org/ -
Errno::ETIMEDOUT: Connection timed out - connect(2)
(*ttps://rubygems.org/latest_specs.4.8.gz)
I connect to the Inet through a 3G modem.
I waited for 6 hours with hope that the site temporarily down for some
reason and tried later. Nothing changed. I tried to install and remove
programs using apt-get instal/removel. Works fine.
I put the line *ttps://rubygems.org/latest_specs.4.8.gz into the browser
and tried to download the file directly using browser. It redirected me to
*ttps://s3.amazonaws.com/production.s3.rubygems.org/latest_specs.4.... and
the result is "This webpage is not available". Then I put the line
*ttps://s3.amazonaws.com/ into the browser and visit the site
*ttps://s3.amazonaws.com/. Again it failed: This webpage is not available.
Later I tied to visit the site *ttps://aws.amazon.com/. It didn't make me
wait too long. I easily open this site.
I also tried to get a page from *ttps://s3.amazonaws.com/ using wget. This
is the result: bayram@bayram-R530-R730:~$ wget *ttps://s3.amazonaws.com/

And finally this is output from traceroute command
