Tor is slow right now. Here is what is happening.

For at least 7 months, several different types of ongoing denial of service (DoS) attacks have affected the Tor network. At some points, the attacks impacted the network severely enough that users could not load pages or access onion services.

We have been working hard to mitigate the impacts and defend the network from these attacks and we will continue to increase and tweak defenses to combat this problem. We've also added two new members to our Network team who will be solely focused on .onion services development.

You can help too! We are 70% towards our goal of fully funding two years worth of onion service development to mitigate the impacts of these attacks and we need your help to get there. Here's how:

New: WhatsApp user support for Tor users

Providing support and necessary tools for those who find themselves in places where Tor access is restricted has become one of our top priorities. As our community continues to grow, we need to make it easier and safer to connect with us. Which is why we have been adding additional support channels for the last two years: from IRC bridges to messaging apps like Telegram, Signal and—most recently—WhatsApp.

To ensure that you receive the best and safest support from us, we encourage you to verify that you're connecting with us through our official Tor Project channels. You can find the full list of legitimate links, email-addresses and numbers on our official support page. And to learn more about the best ways to connect with us across channels check out our recent blog post

What others are saying: Tor in the media

On March 6, the Twitter onion service certificate expired, effectively taking the onion site offline. We took to the media to voice our concerns about this development. Seeing the onion service, which was dubbed "Twitter’s Most Important Anti-Censorship Tool", go offline on the eve of Twitter's new leadership speaking publicly about building a "strong foundation of free speech" at a Morgan Stanley conference, is particularly ironic.

Let’s be clear, the need for onion services, the use of privacy-focused browsers that protect people's anonymity, and other forms of encryption still persists. We will continue to spread this message and advocate for widespread acceptance and adoption of our services.

Welcoming new board members to the Tor Project

We are excited to announce the result of our open call for board members - three new members are joining the Tor Project’s Board of Directors: Esra'a Al Shafei, Sarah Gran and Christian Kaufman!
