How does the status checker work?
We recalculate the status of the service every 30 minutes based on user reports submitted within the last 24 hours. This allows us to provide firsthand information on outages and helps to better understand the extent of the problem.
To do this, we first calculate a baseline — the average number of reports received in 30-minute time blocks over the past 24 hours. This helps us understand what “normal” activity looks like at any given time.
Once we have the baseline, we set thresholds to determine the status of the service:
Online: If the number of reports falls below 50% of the baseline, the service’s status is shown as “Online,” meaning everything is functioning normally.
Partial outage: If the reports fall between 50% and 75% of the baseline, the service might be facing some issues. We label this status as “Partial outage.”
Down: If the number of reports exceeds 75% of the baseline, the service is considered “Down,” indicating significant issues or an outage.
