BNG was recently changed in my region from Juniper to possibly Nokia and I have noticed it happening after that. Could be unrelated but something is definitely happening. I noticed phone light goes off and session disconnects too now, previously session used to stay up during the period. Either they are doing some work and causing this or it's a configuration and compatibility issue.
 
Hey,

I had a similar issue before and I know it’s frustrating. Try updating your router’s firmware; that fixed things for me once. It’s also a good idea to clear your browser cache regularly. Check your router’s QoS settings in case they need adjusting. Make sure no background apps are hogging bandwidth. If none of this helps, it might be an ISP-level issue, so contacting BSNL could be your best bet.
 
Might be early to say but the issue seems to be fixed on my end. No sudden internet disruption since yesterday afternoon. Fast.com which used to be in single digit latency before the BNG change is back. Since the issue was more frequent the past few days I decided to call LCO yesterday and inform them but they were already on it, maybe others complained too.
 
Is anyone getting 10.0.X.X as 2nd and 10.219.X.X 3rd hop while traceroute on BSNL FTTH.I have even tested traceroute of the Assigned IP but There is only 1 hop and it’s the assigned IP
I also checked router Network page.
Gateway
IP is 117.X.X.X and Assigned IP is 117.X.X.X
Is BSNL assigned/Introduced CG-NAT after the new BNG or the MTNL-BSNL Merger ?
NOC-Bangalore
State-KL

@Sanemi I'm getting 10.219.25.x as 3rd hop while traceroute on BSNL FTTH.

No. I don't think BSNL will ever introduce CG-NAT on there new BNG as I've got new BNG assigned in my area on the starting of June which assign 117.x.x.x.x IP address always. (confirmed from NIB after my complaint)

So, You are not on CG-NAT.
 
I have no idea about the original discussion about slowness and not going to comment on it. But this one looks like a interesting question by @Sanemi
I may be dumb to ask my doubt . BSNL has tier 1 isp upstream like Cogent,Tata communications (US),PCCW and HE ,NTT .but the international speeds are low and latency is worse. I get these upstream in most of the ip’s but I have experience most of the traffic routes through the Tata Communications (India).I’ve also faced some slow speed and slow performance issues on some ip prefixes
Click to expand...

You might be making this opinion that they use only Tata Comm becuase you see traces going outside of India via as6453.net. Keep in mind BSNL is a large eyeball network and is mostly inbound heavy. Thus they try to optimise route and load circuits in inbound direction. For outbound they can pretty much use anything. Most of retail traffic has 20-25% outbound compared to inbound. Inbound traffic often is carried by a set of those upstreams you mentioned. So instead of focusing on trace from BSNL > outside world, look for traces from outside world to BSNL.

Full disclosure: I work for one the network you mentioned in the list and as part of my job stare at routing table all day long.
