Us East server issues for DDOS protected ranked games

When the shield icon (DDoS protection) is enabled in Ranked (typically from mid- to high-Plat and above), the game develops consistent issues:

• Packet loss in random waves
• Microstutter and sluggish feeling movement
• Occasional large packet loss spikes causing delayed response (e.g., pressing F to ping, and the ping registers 1–2 seconds later)

This only occurs when the shield is active. Unranked or custom matches (no shield) do not have this problem.

Steps to Reproduce:

1. Queue into Ranked on US-East-1.
2. Reach a lobby/match where the DDoS shield icon is visible.
3. Observe packet loss, stutters, and delayed inputs.

Expected Result:

Normal, smooth gameplay without packet loss or input delay, as seen in Unranked or Customs.

Actual Result:

When shield is active in Ranked:

• Packet loss waves (small and large)
• Microstutter / sluggish motion
• Delayed responses to inputs

Notes:

• Issue seems tied to DDoS protection filtering on Ranked US-East-1.
• US-Central-1 Ranked with shield active does not show this behavior.
• ISP and hardware ruled out — issue is repeatable and specific to shielded US-East Ranked servers
  + If I’m paired with friends, they notice these same issues at the same time
