[Starlink] Re: New Customer or route leak?

[Jianping Pan <pan@uvic.ca>]

given so little jitter, more likely just transit through starlink backbone instead of community gateway, although a longer sequence with a shorter interval will be more conclusive as well

A link to the article with several details I've not and won't mention.

https://www.thedailystar.net/business/news/bangladesh-approves-starlink-export-unfiltered-internet-bandwidth-neighbouring-countries-4216406

>Summary from elsewhere that's clearly wrong in practice

Bangladesh approved Starlink’s bandwidth export proposal.
• Traffic will serve foreign customers only.
• Initial capacity request: 40 Gbps.
• Scalable up to 400 Gbps.
• Bandwidth expected via BSCCL
