A friend of mine buzzed me yesterday about his missing route objects. Later multiple other ISPs told the same story which triggered me to put this as a question on INNOG Mailing list. Many folks replied of missing route objects there and it seems to be limited to IRINN members only. I also asked the same question on APNIC mailing list and it was again confirmed about the issue.
Before I proceed further, here’s what it is all about.
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.
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.
dig btcl.com.bd @8.8.8.8

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.
Today a friend from Pakistan informed about SMW4 outage. He reported about issues in Pakistan.
It seems like SMW4 is damaged near Egypt and that is what causing high load on East Asian routes giving pretty high latency.
I am at my home and sitting BSNL’s network and latency with Europe has jumped terribly to 700-800ms. Right now I do not see a direct route to Europe and it’s rather taking East Asia > US > Europe routes right now on other cable networks.
