Not really sure how that was impacting you, but OnlyTech and some other sites were not "specially" affected when the current issue was going on
for me. Jio's routing issue in Cloudflare free plan sites are still there.
For me, only sites which were routing me through Cloudflare's Mumbai co-location were affected. For example, Cloudflare's own website and Discord were also affected. However, I think they have actually fixed this issue. It seems to be fine since yesterday.
Now, coming to Jio's routing to Cloudflare free sites. Check your co-location from
here for OnlyTech. In the
colo section, it should be BOM (Mumbai) for me but right now I am seeing SIN (Singapore), which is still better than usual right now. This routing, doesn't remain stable though. It will randomly choose Singapore, sometimes US, Canada or Europe.
I don't think Jio will peer with Cloudflare, so I don't think sites with no Argo or premium plan will ever have decent routing with it.
