It's just some DNS issue, just use Google DNS or Cloudflare DNS and it works just fine. I had posted last night about the same in the other thread. The IP address returned when using Spectra default DNS server goes through some weird routing. (Similar when using Jio DNS)
It doesn't seem like being blocked intentionally, could be a configuration error too, maybe Reddit's or maybe Jio's As can be seen above, depending on the which DNS server I use, I get different IP addresses. The 192.168.1.1 is my JioFI device, and the IP address retuned from Jio DNS Servers...
Well, Reddit (fastly in this case) controls what IP addresses are returned when a query is made to their name servers. And as I had posted earlier, that response changes depending on who is asking the fastly name servers.
When Spectra's DNS resolver queries the record, fastly returns an IP address which isn't properly routable on that network. Now who's fault is that? When Google DNS servers queries, fastly says go elsewhere, and when Cloudflare asks, it says go to another place altogether.
Clearly fastly here is trying to optimise the path so that we get pointed to their closest edge location. That mechanism could have very well gone wrong, or they may have tie up with carriers and the required configuration changes weren't propagated.
My point is, this is a special case, and I wouldn't put the blame on the ISPs entirely as things can go wrong at either places.
