Atlassian Statuspage used to set tracking cookies on their customer status pages. Of course me as a single customer asking to remove the tracking cookies had minimal if any effect. So I crawled a list of Atlassian Statuspage customers, contacted them asking to also open support tickets. And indeed it worked, the tracking cookies got removed :-)
