IMSLP went back online on June 30, 2008. Since its reopening, the site has been using a strict copyright policy wherein uploaded files are made accessible for download only after the copyright status for three most frequent copyright regimes has been reviewed by staff members. Although the server is located in Canada, files that are not public ___domain in the US were until July 2010 flagged [TB], for 'Technical Block' or 'Temporary Block', and could not be viewed. The FAQ posted in their forum stated, "Unfortunately, these 'temporary' blocks will be until further notice – possibly all the way until the expiration of term in the USA."<ref>{{cite web|url = http://198.137.202.16/viewtopic.php?f=6&t=3319|title = FAQ Works in TB Status|access-date = 2010-05-22|archive-url = https://web.archive.org/web/20120331064636/http://198.137.202.16/viewtopic.php?f=6&t=3319|archive-date = 2012-03-31|url-status = dead}}</ref> After an initial phase, [TB] flagged items have essentially disappeared thanks to the introduction of regional servers operated by unaffiliated organizations.
