It could be argued that the title is just plain wrong - this doesn't seem to be a problem with cloudflare as the title would imply, it is an issue caused by the user's ISP and other ISPs in their country blocking certain IP addresses for some reason or another.
Well, this is tantamount to saying "X Server is Slow"—when accessed from Japan, when your server is in a datacenter in North America. I know we're talking India here, but it's a personal experience, my server wasn't slow, but felt like it in Japan. There is a specific context that yielded this result, and that's important to actually having a meaningful story that isn't just clickbait for a blog on HN.
In this particular scenario, CloudFlare isn't slow, but their experience of accessing it under the context of x circumstance is.
But it does matter who is to blame. Cloudflare's service works as intended. The only problem is with incompetent oppressive governments, which is not something they can account for, not should they be expected to.
