  • Why: BGP operations at 26-million-prefix scale is the extreme end of BGP tooling and datapath internals — exactly what the PM tracks in software networking.
  • What: How BGP operations were reworked to select and serve the "best" prefix out of a 26-million-prefix table. (title only)
  • How: Unknown; at that scale this is necessarily automation and policy engineering around massive tables — the deck has the architecture.
  • Where applicable: The 26M figure signals a very large content/anycast or transit platform, so the scale is org-specific; the tooling and automation patterns partially transfer.
