[Myanmar] Severe Internet Slowdown & VPN Connectivity Issues (Since Nov 1st) - Firewall or Cable Issue?

Beginning November 1st, 2025, Myanmar users reported severely asymmetric internet speeds: download speeds were near-unusable while upload speeds remained at normal maximum capacity, a pattern inconsistent with submarine cable faults which typically degrade both directions.

Community technical analysis of the November 2025 Myanmar disruption concluded the observed symptom cluster — unidirectional throttling, rapid VPN IP blocking, and selective service allowlisting — is inconsistent with submarine cable faults and instead indicates deployment of new national-level traffic filtering infrastructure, consistent with GFW-derived Geedge filtering technology previously documented in Myanmar.

A freshly provisioned VPN server in Myanmar was functional for approximately 5 hours before its IP address was completely blocked across all connection methods, indicating the Myanmar filtering infrastructure performs rapid active detection and IP blacklisting of new proxy endpoints.

During peak disruption periods in Myanmar (post November 1st, 2025), users observed a 'walled garden' effect where the entire internet dropped except for Google and YouTube, which remained selectively accessible — consistent with allowlist-based national firewall policy rather than infrastructure failure.
