Partial outage on .bd ccTLD on 5th Oct 2016

outage Bangladesh’s .bd ccTLD faced another outage. As I mentioned in one of the previous posts - .bd domain seems to be primarily on BTCL (AS17494).  Zone delegation of .bd is still pending with PCH and while PCH is mentioned in NS records of the authoritative DNS servers but delegation is pending in the root DNS servers as per reply from Kabindra from PCH on the bdNOG mailing list during the last outage.

IPv6 Only Web Hosting

Saw this excellent presentation in UKNOF 34 by Peter Stevens from Mythic Beasts. Really enjoyed the challenges and fixes he shared in running an IPv6 only web hosting. A must watch for geeks :)  

Also, UKNOF & NLNOG both seem to have excellent content in their conferences along with professional video recording which they make available over YouTube channels.

Tata Communications (AS4755) pushing traffic to Reliance Jio (AS55836) via Singapore!

So it seems like apart from voice interconnect issues, Jio is also facing routing issues on the backbone. I ran a trace to one of IP’s on Jio network allocated to end customer - 169.149.212.122. I ran trace from all Indian RIPE Atlas probes measurement here. There seem quite a few RIPE Atlas probes which are giving latency on 150ms + range. Seems like they are downstream or downstream of downstream of Tata Comm’s AS4755 and routing is happening via Singapore!    

IPv6 allocations to downwards machine with just one /64

IPv6 One of my friend went for a VM with a German hosting provider. He got single IPv4 (quite common) and a /64 IPv6. Overall /64 per VM/end server used to be ok till few years back but now these days running applications inside LXC containers (OS level virtualization) make more sense. This gives option to maintain separate hosting environment for each application. I personally do that a lot and infect blog which you are reading right now itself is on a LXC container.
