In Hong Kong and right on the day when I was leaving for Hong Kong - I noticed a bug in my Macbook Pro’s screen. A real insect yes!   ![img_20160907_151934]https://cdn.anuragbhatia.com/web/post/2016/09/three-days-without-laptop-repair-of-damaged-macbook-pro-screen/images/IMG_20160907_151934-scaled.jpg)

This was irritating. Hard to know how it actually got inside but may be from bottom side of laptop which was missing two screws for a while which I recently bought from UK and added. Apple support couldn’t answer on how it got there. Furthermore I was facing a problem of screen showing pink/green lines after turning on for almost 1.8 years now. They used to show up when laptop was turned on and used to go away after 15-20mins. Over time the issue increased and now it was taking as much as 40-50mins for lines to go away. Since I was visiting Hong Kong for HKNOG 3.0, I booked an appointment with Apple store. Fixing time went quick (over phone call with Apple support) and I was at Apple store in HK right on next day after an overnight flight to Hong Kong. They dropped bill bomb by quoting me $5600 HKD / $720 USD / 48k INR !!!

Day before yesterday i.e on 18th August 2016 Bangladesh’s TLD .bd went had an outage. It was originally reported by Jasim Alam on bdNOG mailing list.

His message shows that DNS resolution of BTCL (Bangladesh Telecommunications Company Ltd) was failing. Later Alok Das that it was the power problem resulting in outage. Let’s look ask one of 13 root DNS server about NS records on who has the delegation for .bd.

Just noticed that Reliance Jio (AS55836) seems to be originating a /16 which is for Charter Communications (AS20115) - 47.35.0.0/16.

This shows Reliance Jio’s ASN AS55836 announcing 47.35.0.0/16. Charter Communications (AS20115) is originating multiple of /18s out of the same pool.  

So last week I couldn’t hold off my curiosity about world famous address “221b Baker Street”. I passed “Baker Street” tube station quite a few times and finally decided to just look for it. :) By time I reached the street it was lightly raining and I found few other (curious) people like me standing outside 221b Baker Street. It has got a museum for Sherlock Holmes (though was closed by the time I reached).

It’s great to see Amazon announcement two days back about launch of their region in Mumbai. In past I was quite happy to see their Cloudfront CDN PoPs in Mumbai & Chennai (blog post here). Now it’s just great to see a full AWS region out of Mumbai. :) Though it’s going to eat most of important customers from the smaller players still it’s good for industry as industry is too big and we need more & more of such large Cloud players in India to bring more and more content hosting in India.
