The ping test results show significant variation in response times (ranging from 8ms to 52ms) when connecting to two specific data centers from your new office location. This jitter wasn't present in your previous office setup. Interestingly:

# Sample ping output showing variation
for i in {1..10}; do ping -c 1 123.123.123.123 | grep "time="; done

To properly diagnose, we should first map the network path using traceroute:

# Windows:
tracert 123.123.123.123

# Linux/Mac:
traceroute 123.123.123.123

Compare these results with traceroutes from your old office and to the stable third data center (100ms consistent). Look for:

• Different routing paths
• High latency hops
• Packet loss at specific points

The inconsistent ping times could stem from:

# Common causes of network jitter
1. Network congestion at specific times
2. Faulty networking equipment (switches, routers)
3. Suboptimal routing configuration
4. Wireless interference (if using WiFi)
5. Bandwidth throttling by ISP

For more comprehensive analysis, consider these tools:

# Continuous ping monitoring
ping -t 123.123.123.123 > ping_log.txt  # Windows
ping -i 1 123.123.123.123 > ping_log.txt  # Linux/Mac

# MTR (combines ping+traceroute)
mtr --report 123.123.123.123

Based on the findings:

# If congestion is the issue:
1. Implement QoS policies
2. Upgrade network infrastructure
3. Change ISP or routing

# If routing is suboptimal:
1. Contact ISP about better routes
2. Implement direct connections (VPN tunnels)

# If equipment is faulty:
1. Replace/upgrade switches/routers
2. Check cable quality (use Cat6 or better)

Set up continuous monitoring with tools like:

# Simple bash monitoring script
#!/bin/bash
while true; do
  ping -c 10 123.123.123.123 | \
  awk '/min\/avg\/max/ {print $4}' >> latency_log.csv
  sleep 300  # 5 minute intervals
done

The ping results show significant variability (9ms to 52ms) when communicating with two data centers, while maintaining stable latency (~100ms ±3ms) with a third location. This jitter specifically occurs after an office relocation, suggesting infrastructure changes as the likely culprit.

First, let's gather more comprehensive network metrics:

# Continuous ping with timestamp logging
ping -n 30 -w 1000 123.123.123.123 | Foreach{"{0} - {1}" -f (Get-Date),$_} > ping_log.txt

# Pathping for route analysis
pathping -n 123.123.123.123

# TCP connection test (PowerShell)
Test-NetConnection 123.123.123.123 -Port 80 -InformationLevel Detailed

The office relocation likely introduced one of these scenarios:

• New network equipment with improper QoS configuration
• Different physical routing through intermediary nodes
• Wireless interference if using Wi-Fi in the new location
• VLAN misconfiguration causing packet prioritization issues

For developers needing precise measurements, consider implementing a Python network probe:

import ping3
import statistics

def analyze_jitter(target, count=30):
    times = []
    for _ in range(count):
        delay = ping3.ping(target, unit='ms')
        if delay is not None:
            times.append(delay)
    
    print(f"Average: {statistics.mean(times):.2f}ms")
    print(f"Jitter: {statistics.stdev(times):.2f}ms")
    print(f"Max variation: {max(times)-min(times)}ms")
    
analyze_jitter("123.123.123.123")

For immediate improvement while diagnosing:

1. Configure ICMP priority on network devices:

   # Cisco example
   access-list 100 permit icmp any any precedence immediate
   

2. Implement traffic shaping if bandwidth contention exists
3. Verify duplex settings on office switches (full/half)

Consider involving network engineers if you observe:

• Persistent packet loss (>1%)
• Jitter exceeding 30ms consistently
• Visible routing loops in traceroute
