The mystery of the routes that refused to die#

Andrés Pugawko

• Why: By title, a routing postmortem — routes that persisted after they should have been withdrawn — which is exactly the sticky-state / withdrawal-propagation class of BGP datapath bug the PM cares about, and postmortems are the highest-transfer format at operator events.
• What: The program publishes no description for this talk, and no source text was available, so this entry reflects the title and speaker only. Judged by the title it is a troubleshooting narrative about routes that survived expected withdrawal; anything beyond that requires the slides or recording.
• How: Not determinable from the program text; slides and video are published.
• Where applicable: Unknown until reviewed — flagged here because the format and subject area are high-value for this reader.
