What the fuck is this and why does it show up for me on sites such as:
>sci-hub
>nyaa
>fitgirl repacks

Can't find a single proper explanation for it anywhere, just retards saying "use vpn", which granted, works, but I want to know WHY it's even happening to begin with.
All these sites are on DDoS-Guard, but given that RT and other non-piracy sites that use it work just fine, I doubt it's an issue with them.
On the other hand, the error page is being presented by the site itself using a valid SSL certificate, so I highly doubt it's some ISP fuckery and it seems more like a serverside issue.

>Traceroute shows the connection routing to Arelion's Moscow/St. Petersburg nodes before timing out, but this doesn't seem indicative of anything, more like DDoS-Guard just doesn't respond to pings since it times out on RT too, which is perfectly accessible.
>The actual DDoS-Guard IPs are also accessible directly and instantly return a 503 error, the 504 page is only presented when accessing certain domains (it's not a DNS issue either).
>Looking at BGP paths through Arelion's Looking Glass tool (using kbn-b1 Copenhagen) I noticed that all the DDoS-Guard sites that "work" generally have "communities" that say "(Prepend 3x to X in Europe)" and that the two ASNs listed are "59692 57724" whereas those that time out don't have those "communities" and the listed ASNs are "59692 59692", but that's based on a sample size of ~4, and I know fuck all about network engineering so that could be completely meaningless.
>VPN works but varies by country, Denmark times out just the same but Netherlands/US both work.

Definitely not a new issue, pretty sure it's been happening for at least a year now.
At first I thought it was ISP censoring but the valid SSL certs now make me think otherwise, any anons know what the fuck is going on?

whenever there's a gateway timeout it's because they left the gate open for too long

afaik fatgirl's website is getting ddos'd very frequently. I haven't been able to access it (from scandinavia) in couple of months now.

Funnily enough I was able to find more discussion of this issue just by searching "arelion" or "twelve99" in the archives (though still no proper explanation) and it was largely finns/swedes, is this a scandinavia-only issue or something?
If it was a DDoS then I don't see why the sites all work just fine via Tor/VPN (or at least from most VPN countries). And if it's not DDoS then the more likely option is censorship, but that doesn't explain how the connection is still reaching its destination to some extent, since the error page uses a valid certificate for that domain.
I really don't get what's going on.

The MitM server that sits between you and everything on the modern web has the SSL cert from the original site uploaded to it. So it can LARP as the original site and modify all content in real time.

Welcome to hell.

If there are multiple servers for lets say a web application where one of the servers acts as a gateway to the web application and it is unable to connect to it within the configured time then it timesout
