How Pong.com Helps Sparklight Customers

Most speed tests only measure raw throughput inside your ISP's network. Pong.com goes further, testing across the real public internet to reveal what your Sparklight connection can actually do.

Bufferbloat Detection

Discover if your Sparklight connection suffers from high latency under load. Bufferbloat causes lag and stuttering even on fast connections.

Jitter Analysis

Measure the consistency of your Sparklight connection. High jitter means unreliable performance for gaming, video calls, and streaming.

Connection Health Grade

Get an A-F grade for your Sparklight connection based on speed, latency, bufferbloat, and stability. Know exactly where you stand.

Real-World Experience Scores

See how your connection performs for specific activities: 4K streaming, video conferencing, competitive gaming, and web browsing.

Speed History Tracking

Track your Sparklight speeds over time. Spot trends, identify peak-hour slowdowns, and catch degradation before it becomes a problem.

Public Internet Testing

Unlike tests that measure inside Sparklight's network, Pong.com tests across the real internet, giving you speeds that match your actual experience.

Sparklight FAQ

Is Sparklight throttling my internet?
If your speed test results are significantly lower than what your Sparklight plan advertises, throttling or network congestion could be the cause. Run a test on Pong.com to check your real speeds. Pong.com tests through the public internet (not inside Sparklight's own network) so you get an accurate picture. Try testing at different times of day to see if speeds drop during peak hours.
What speeds should I expect from Sparklight?
Sparklight offers download speeds of 200 Mbps and upload speeds of 20 Mbps, depending on your plan and connection type (Cable, Fiber). According to FCC Measuring Broadband America data, on a wired Ethernet connection you should typically see 70-90% of your plan's advertised speed. Wi-Fi speeds will be lower due to signal attenuation and interference. Use Pong.com to verify your actual speeds.
Why is my Sparklight internet slow even with a fast plan?
Several factors can slow down your Sparklight connection: bufferbloat (high latency under load), Wi-Fi interference from neighboring networks, outdated modem or router firmware, network congestion during peak hours, or issues with your home wiring. Pong.com tests all of these factors in a single test, including bufferbloat detection, jitter analysis, and a connection health grade.
Does Sparklight have bufferbloat problems?
Bufferbloat can occur on any ISP connection, but it is especially common on Cable connections. It causes your latency to spike when your connection is under load (e.g., downloading a file while on a video call). Pong.com specifically tests for bufferbloat and grades it from A (excellent) to F (severe). This tells you more about your real connection quality than download speed alone.
