Live from apartment 2209. A computer plugged in by cable checks the building's internet every second, day and night. Test your own apartment →
Every apartment's internet goes through the building's router first. It's in the same building, so it should reply almost instantly, every time. Times are in ms, thousandths of a second.

Each square is one second. Each row is one minute, read left to right, with the newest at the bottom. Red and black squares are moments when the internet froze or dropped out. "Speed test" marks minutes when this computer was running its own speed test, which can slow things a little.
Each bar shows how much of that stretch of time was good, slow or broken. Red and black means the internet was unusable.
Lower is better. The coloured zones show what each reply time feels like. Each gridline is 10 times the one below, so huge spikes still fit. Blue stripes mark this computer's speed tests.
Reply times from four places: the building's router, the next stop on Lightning Broadband's network, and Cloudflare and Google out on the internet. The lines rise and fall together, so the delay is already there at the building's router. Everything further away just inherits it.
Measured every 5 minutes. The plan is 100 Mbps.
Apple's responsiveness score, measured while the connection is busy downloading. Higher is better. A healthy connection scores over 1,000.
Stretches of time when the internet was badly lagging (1 in 10 replies took over half a second) or dropping out (more than 5% of replies never came back).
