  • HIGHBRIDGELDN's AS24910 is a retired London enterprise edge, not a regional ISP

    The registry still assigns AS24910 to JPMorgan Chase & Co, but public route collectors have not seen the network originate a prefix since December 2019. Its London address block is now announced by Amazon, the UK company once associated with the Highbridge office was later dissolved, and Highbridge still describes a London research presence. This is not evidence of a subscriber network. It is the record of a compact institutional edge being retired while control of names, addresses, connectivity and recovery moved across corporate, carrier and cloud boundaries.
