Internet users who have been trying since noon Monday to obtain tickets for the extras of the show highlighting the 50th anniversary of the album The Dark Side of the Moon at the Montreal Planetarium have come up against a maintenance page on the Espace pour the life.

According to Space for Life, the large influx caused an overload of computer systems and a breakdown of the website. The restoration of the site will be announced on the Space for Life Facebook page and Twitter account.

The additional sessions are scheduled from September 8 to December 23, while those in progress are sold out.
