 ### Analysis
 
-The traceroute measurements reveal several important network characteristics:
-
-* Round-Trip Time Analysis
-  - Measurement 1 (14:34): Highest average RTT (34.34 ms) with largest standard deviation (25.61 ms), indicating significant network variability
-  - Measurements 2 & 3 (14:39, 15:08): Similar performance with averages around 15.4 ms and standard deviations around 9.1 ms, showing more stable conditions
-* Router Path Analysis
-  - Measurement 1: 13 hops - took a longer path through Google's network infrastructure
-  - Measurements 2 & 3: 8 hops - more direct routing to the same destination IP (142.251.215.238)
-  - The hop count reduction suggests load balancing and route optimization occurred between measurements
-* Network Behavior Patterns
-  - Initial measurement showed higher latency and variability, possibly due to:
-    - Cold cache effects
-    - Different routing through Google's CDN
-    - Network congestion at that time
-  - Subsequent measurements benefited from optimized routing and reduced congestion
-  - The consistent performance in measurements 2 and 3 indicates stable network conditions during that timeframe
-
-Key Findings:
-
-1. Route Optimization: Google's network dynamically selected shorter paths for better performance
-2. Time of Day Effects: Network performance improved over the 30-minute measurement window
-3. Latency Consistency: Later measurements showed lower variability, indicating more predictable performance
-4. Load Balancing: Different destination IPs (142.251.32.78 vs 142.251.215.238) demonstrate Google's distributed infrastructure
+The traceroute runs show different destination IPs due to Google's
+load balancing. Trace 1 took longer (61ms, 13 hops) while Traces
+2-3 were faster (21ms, 8 hops), indicating route optimization. The
+`* * *` entries show routers filtering ICMP traffic, which is normal
+behavior.
