List Of Services Blocking Tor

The Tor community maintains the following three lists (RBL blocks, Blocking software, and Individual blocks) as part of the DontBlockMe project. It is the opposite of the WeSupportTor project.

Glossary

CDN - A C ontent D elivery N etwork: these are networks that websites use to serve high amounts of traffic to their clients. CDNs can be geographically distributed to provide "local" copies of web content to people worldwide.

ontent elivery etwork: these are networks that websites use to serve high amounts of traffic to their clients. CDNs can be geographically distributed to provide "local" copies of web content to people worldwide. Exit relay - This is a Tor relay that exits traffic onto the plain Internet. All Tor traffic (though not when using onion services) appears to originate from these exit relays.

Non-exit relay - A Tor relay that does not act as an exit relay. A non-exit relay does not originate any traffic other than to other Tor relays and thus there is no necessary reason for services to block traffic from them. Guard and middle relays are the two types of non-exit relays, and many non-exit relays act as both types at the same time.

TCP RST - The TCP reset (or reject) is a way to gracefully close connections. Many services/software to block Tor traffic may block by explicitly closing the connection instead of ignoring the traffic.

TCP timeout - A TCP timeout is another way to block Tor traffic on the protocol- or routing-level, however it involves silently ignoring the traffic instead of rejecting it.

List of RBL Blocking Services

An RBL is a "realtime blackhole list" which is a DNS query-based list used to tag IP addresses as being malicious or as being an origin of spam. Due to the inability to filter or monitor Tor user behavior across the entire network, many Tor exit relay IPs will be marked as threatening (even indiscriminately) which means many legitimate web surfers will be incidentally included in such blocks. This is a subproject to routinely search for and clear Tor relay nodes from RBL and RBL-like lists.

Format:

[URL] - Description of service/list, threat detection and consequences for Tor users

List Of Software Used To Block Tor

A listing of the software that has been identified as being used by the services listed below. This can present via another avenue to accomplish the goals of the DontBlockMe project. The format is:

[URL] - How to identify the blocking software when used by a service

How to unblock Tor users

See: Best Practices. If you run a web site on Cloudflare, and you don't want Tor users to see captchas, then whitelist the "T1" country code in the ​Access Rules of the Cloudflare Firewall app. See ​this article for more information. The best option is not using Cloudflare at all. There are many alternative self-hosting options. See The Great Cloudwall? for more information.

Ad-hoc Solutions for accessing blocked content on Tor

There are various ad-hoc ways by which Tor Browser users may access websites that block Tor. All of these solutions involve fetching content via other websites, a privacy tradeoff.

Service URL Comment Allows embedded non-static content? Allows PDF/.exe/mp3? The Internet Archive's WaybackMachine web.archive.org/save/_embed/<URL> Archive.org respects robots.txt restrictions, works best with JS enabled No Yes Archive.fo archive.fo/?run=1&url=<URL> And their official onion service: archivecaslytosk.onion/?run=1&url=<URL> Ideal for news sites, doesn't require JS No No Google Cache webcache.googleusercontent.com/search?q=cache:<URL without "http://"> Google sometimes blocks these requests No - static only No Startpage.com (1) Find the URL by searching, (2) Click on the proxy option Not always efficacious No No Searx.me (1) Find the URL by searching, (2) Click on the proxied option Not always efficacious No No Hypothes.is via.hypothes.is/<URL> Behind Cloudflare Yes Yes Online Proxies hide.me/en/proxy Yes Yes www.proxysite.com/ Yes Yes www.proxysite.club/ Yes Yes hidester.com/proxy JS disabled by default Yes Yes youtubeunblocks.com/ JS disabled by default Yes Yes

Other relevant services

To avoid captchas that are often required when visiting YouTube, use ​ this. To avoid captchas that are often required when visiting YouTube, use hooktube.com/ (behind Cloudflare recaptchas).

imgur.com blocks Tor uploads, to upload images on an imgur domain go to a stackexchange website (for example tor.stackexchange.com ), click on Ask a Question , use the image upload tooltip to upload the image, the resulting url will have a i.stack.imgur.com/... form.

Field guide to common block pages

Akamai

Access Denied You don't have permission to access "%websitename%" on this server. Reference #[\d\.a-f]+

​Akamai is a CDN.

Bad Behavior

​Bad Behavior is an antispam PHP plugin.

Blackbaud

Not implemented Tor IP not allowed.

​Blackbaud does web hosting for nonprofits.

Bluehost

​Bluehost is a web hosting company. This seems to be their source code that is the source of the message: ​mod_rbld.

Cloudflare

One more step Please complete the security check to access %websitename%

​Cloudflare is a CDN acting as MITM by design, decrypting all TLS (HTTPS) traffic to plaintext and harming users privacy by (feature called flexible SSL) intransparently forwarding traffic from https end-user in plaintext to origin webserver most of time. See The Great Cloudwall?.

Distil

Access To Website Blocked

​Distil Networks is an anti-bot/anti-scraping company. They also have challenge pages that are less severe than this block page (which has status code 456).

imperva

%websitename% - Additional security check is required Why am I seeing this page? The website you are visiting is protected and accelerated by Incapsula. Your computer may have been infected by malware and therefore flagged by the Incapsula network. Incapsula displays this page for you to verify that an actual human is the source of the traffic to this site, and not malicious software. What should I do? Just click the I'm not a robot checkbox to pass the security check. Incapsula will remember you and will not show this page again. We recommend you run a virus and malware scan on your computer to remove any infection. Powered by imperva

Imunify360

List Of Services Blocking Tor

Services should be listed if:

They display a written policy that prohibits "Tor" specifically by name.

They display a written policy prohibiting proxies, VPNs, open/free networks, travelers, etc.

The text of an error message indicates "Tor", anonymous proxies, etc.

After testing with "signal NEWNYM / New Identity / MAPADDRESS", access and/or full use via Tor is found to be consistently problematic (defined as affecting at least 80% of all exits).

The list is formatted in alphabetical service groupings as follows:

URL of service - nature of block: complete, account creation, read-only, random breakage, etc. [last check: <current date in YYYY-MM-DD>]

Attention: Please be aware, that this page itself (​https://trac.torproject.org) does block Tor traffic for registration and editing by showing very hard to read captchas. Try: ​http://ea5faa5po25cf7fb.onion/projects/tor/register

List of formerly listed services

These were formerly listed in the above list, but someone (you) found that they now seem to work "more often than not" and thus moved them here adding the move date (do not remove the original reason for listing). Once listed here, other readers will check them from time to time. If they are still blocking "more often than not", feel free to move them back into the lists above. If they've been on this list for over a year, feel free to remove them as apparently having been a temporary IP block, not a complete class-based (Tor/VPN/Proxy) block. Listings older than 3 months should probably be removed.
