Check your provider gives the speed you pay for

Tell it your plan#

1. Find the speeds you pay for, on your bill or your provider's site: a download and an upload speed, in Mbps.
2. Open the Weigher's page (Open on its card in Castellan), and open Settings.
3. Fill in Your plan: download and Your plan: upload, and press Save.

From then on, each sample shows as a share of your plan.

Read the verdict#

Under the fair measure, for the last 7 and the last 30 days:

• The median download, upload and latency, and the share of your plan.
• The samples under half your plan's download.
• The outages, and how long they lasted, and on whose side.
• How much of the time the line was watched.
• The slowest times of the week: weekdays or weekends, by night, morning, afternoon and evening.

And a verdict in plain words, such as: "Over the last 30 days you got a median 82% of the download speed you pay for (41 of 50 Mbps) and 95% of the upload; slowest weekday evenings (61%); 3 outages totalling 47 minutes, 2 of them on the provider's side." The Weigher's code writes it, from the samples.

When the line was watched less than 90% of the time, it says so. Skipped and failed samples aren't counted.

Make it a fair test#

• Use a cable to the router if you can, at least for a while: Wi-Fi often limits the speed more than the line does.
• Raise Download per sample (Advanced) to 50 MB or more if your plan is over 200 Mbps.
• Leave the PC on, with the Weigher on duty, so the line is watched most of the time.

Take it to your provider#

Under Export:

• Samples (CSV): every sample, with its time, speeds, latency, share of your plan, connection and signal, and why any was skipped.
• Outages (CSV): each outage's start, end, length and side.
• A printable report: a plain report with both verdicts, the slowest times, and every outage and sample, to print or save as PDF.

The CSV files open in any spreadsheet.
