Poor Netflix performance on BSNL Bharat Fiber Broadband

I think he just wanted to avoid the hassle of running two devices simultaneously on a single connection.
 
Netflix performance again seemed iffy yesterday with it sometimes switching from 4k to 1080p. But download speeds and browsing (maybe because of pihole) seemed fine.

The picture is worth a 1000 words 😅

I just hope its temporary due to some maintanence🙏. Anyone else, esp from Kerala / tvm facing the same issue?
 
I'm also seeing increased latency to some destinations. Looks like some routing misconfig where the return traffic is taking a weird path?

The IPv6 addresses of CloudFlare and OpenDNS do not show the increased latency.

Had a an isssue loading the page first time. Then it run smoothly on my max speed 50mbps, so far so good.
 
1. Nexflix - App speed is shown as about 30 mbps now (while fast.com shows full 100 mbps). Contents mostly remain in 4k HDR occasionally switching to 1080p. Bearable as of now.

2. Ping to game servers - all over the place since last 2 months atleast. Sometimes its as high as 250 to mumbai. Though im about 1500 kms away, ping to google dns there is 25. So is it too much to expect ping in the same range? Ping to chennai server earlier was best, ~40. Now its 120+.

3. Im still unable to ping quad9 dns either from my home ftth or mobile 3g hotspot :sick: :unsure:

One thing I noticed is now I got IP range 59.xxxxx whereas I usually get 117.xxxx or 61.xxxx range, so maybe Pune NIB has switched to backup system (failover).

@vishalrao , my ip's are also in range of 59. and 117.205. range. One thing ive noticed is restarting modem to change ip range seems to require a lot of tries... eg 5 - 10 restart tries. But once it gets a range of to say 117.205.x.x, it remains in that range of ip for about a week atleast.

Based on reading all three threads about ping spike issues, @varkey 's Ipv6 shenanigans (and as usual @Ameen 's disappointments:p ) and the recent VRS / restructuring etc, I'm hoping BSNL has finally got its act together to rehaul and spruce up its network.

That is weird, I see the same behaviour. The traffic doesn't leave BSNL on IPv4 or IPv6, looks like its blocked.
