The social media service had been using the free version of user-authentication platform Okta, which provides cloud software so that companies can have their users log in remotely.
“We were notified that Parler was using a free trial of Okta’s product and we have terminated Parler’s access to the Okta platform”, the company tweeted.
“While we support organizations across the political spectrum, our platform will not be used for threats of violence and illegal activity.”
It is not currently known precisely what Okta services Parler was using, or how long Parler had been using them for.
Amazon had told Parler that it had seen “a steady increase in this violent content on your website, all of which violates our terms”.
Apple and Google had already removed Parler from their app stores. Google’s ban came on Friday and was followed by Apple, which said it had given Parler 24 hours to fix its moderation issues or face a ban, which went into effect after that.
Parler has since started the process of suing Amazon for retracting its Web Services server support.
Parler accused Amazon Web Services of “political animus” and double standards compared to the treatment given to Twitter.
“AWS’s decision to effectively terminate Parler’s account is apparently motivated by political animus,” states the lawsuit.
Neither Okta nor Parler responded to a request for comment from The Independent before publication.
