[NANOG] Blocked by Reddit
Anyone reading from Reddit? We've been getting a "Blocked by Network Security" page for several (presumably all) of our network blocks and a ticket open with support has gotten no useful replies. Justin H.

Sorry if this isn't the response you were hoping for, but maybe a piling on will help highlight that yours isn't an isolated problem. I've seen this from some random address space too. They seem to dislike some prefixes if they are typically associated with servers for instance, but are perfectly OK with Tor. There seemed to be a change to their blocking about a year or two ago. I've never been much of a reddit user and it seems so arbitrary that I've not bothered to open a ticket with them. Instead I just stop trying to click on reddit links that show up in search engine results. *shrug* John

Last time around it was AWS adding what they considered non-eyeball networks to a global block list. This time (at least so far) it seems isolated to Reddit. It may still be an AWS issue, but I think that would be for Reddit to say at this point. Justin H. Justin
Hi, we (AS21473) are also blocked by reddit and didn't get a response when we tried numerous times over the last year. Amazon is also affected and the only thing they said is, it's because our network is flagged as "hosting" in (at least) one database: https://ipinfo.io/AS21473 Ipinfo responded they won't change the flag because we have customers operating their domains from our IP space, which isn't such a surprise when offering business broadband with fixed IP addresses and high speeds and (additionally) expanding into the data center market.. Not much we can do about it. So, if anyone has ideas (or good contacts), I'm happy to try more :) Thanks Nico On 17.03.2025 20:30, Justin H. via NANOG wrote:

Have you clearly labeled subnets as "broadband connectivity" in arin/ripe dbs? I had this issue with amazon and was able to get them to remove the subnets that were listed as as being used for broadband while leaving cloud/datacenter subnets blocked You need to open the ticket clearly stating the fact that they are broadband subnets and listed as such in the RIR db. I attached copy and links to the allocations. HTH Brian
Thanks Nico

No idea about this from the network perspective, but I want to point out they started intermittently blocking Tor about the same time they had their third-party app tantrum (i.e. early 2023). You get HTTP 429 and a blank screen. Presumably they're not explicitly blocking Tor, but also not exempting it from standard rate limits, making it useless if other people or systems are also accessing it through Tor. Sometimes you can load a few pages. It feels like Reddit's jumped the shark since that time period, not too dissimilar from Twitter. Some people reported that you can now get your IP address banned for upvoting memes about the Nintendo character Luigi. It might have been worth trying to get unblocked if they were still a serious site, but... FWIW they're allegedly blocking all search engines other than Google, who paid them a lot of money for the exclusive right to show them in results and use them for AI training. That's one reason they suddenly switched to trying to keep everyone out. For a while they were specifically trying to block Microsoft because of OpenAI.

I see this intermittently on sites using HE tunnels for v6 connectivity. Reddit has never responded to any support tickets opened/filed. Though, overall, defense measures for sites in general have gotten really hostile to HE IP space in the past year or two (likely due to bad actors abusing the free tunnel service) -----Original Message----- From: nanog--- via NANOG <nanog@lists.nanog.org> Sent: Sunday, March 23, 2025 2:36 PM To: NANOG <nanog@lists.nanog.org> Cc: nanog@immibis.com Subject: [NANOG] Re: Blocked by Reddit No idea about this from the network perspective, but I want to point out they started intermittently blocking Tor about the same time they had their third-party app tantrum (i.e. early 2023).
