When the Pokémon Global Link website launched in Japan in September of 2010, the site had
to close and delay its reopening due to overwhelming Internet traffic. Once again, the Pokémon Global Link website launch is being delayed, this time for languages other than Japanese due to the earthquake and tsumani that devastated parts of Japan last week. The official Pokémon Global Link website has posted the following notice regarding the scheduling change:
"Pokémon Global Link was scheduled to launch on March 30, 2011. As a result of the earthquake in Japan and the need to conserve energy resources, the launch date has been temporarily delayed. When a new launch date is determined, it will be published here on the Pokémon Global Link. We apologize sincerely for any inconvenience caused by this delay."
