Datum a čas: 2021-11-26 00:19 CET Očekavaná délka: 29 minut Oznámení se týká serverů: Production, Playground, Praha storage, Staging, Praha, Playground, Praha Storage, Staging Typ výpadku: network Důvod: Chyba v konfiguraci BGP Výpadek řeší: Pavel Šnajdr, Martin Myška

zrejme tedy... stale patrame, co se stalo; vypada, ze dell os9 switche neumi vyresit BGP zmeny tak rychle, jak potrebujeme (zrejme problem s CPU QoS nastavenim, od tamtud pak nabalujici se koule zpomalenych updatu)

ENGLISH: Date and time: 2021-11-26 00:19 CET Expected duration: 29 minutes Affected systems: Production, Playground, Praha storage, Staging, Praha, Playground, Praha Storage, Staging Outage type: network Reason: BGP configuration error Handled by: Pavel Šnajdr, Martin Myška

most likely... still investigating; looks like dell os9 based switches don't resolve BGP changes as fast as we'd like (CPU QoS config issues likely, snowball effect from there onwards)
