- Meta has a network issue affecting clusters in Boca Raton/Miami, impacting Latin America's content delivery.
- Problem involves packet loss/data corruption, not detectable via standard monitoring tools (ICMP/TCP works, UDP misleading).
- Issue likely stems from BGP/OSPF/IGP instability or faulty hardware between IPs 129.134.101.34, 129.134.104.84, 129.134.101.51.
- Reported 5 months ago; similar unresolved issue occurred in 2023, fixed only after direct interface inspection.
- Monitoring tools fail as they rely on HAR files/QUIC, masking TCP-based issues (e.g., WhatsApp Status slowness).
- MTR/traceroute unreliable due to ECMP/bundle paths not always hitting the faulty interface.
- Reproduction steps: Ping MNA cluster IPs with >500-byte payloads from 157.240.14.15 to observe 10-60% packet loss.
- Solution: Isolate faulty port/hardware.
