Twitter’s privacy-preserving Tor service goes dark

Twitter’s Tor service, a version of the site that could be accessed even in countries where the social network is banned, has gone dark after the company failed to renew its certificate.
The certificate for Twitter’s onion site expired on March 6, just days before the site was set to mark its one-year anniversary. Pavel Zoneff, director of strategic communications at the Tor Project, the non-profit organization beyond the anonymous global network, told TechCrunch that the site “is no longer available seemingly with no plans to renew.”
