SLA credit reckoner
Your host promised uptime. Count what you are owed.
Many hosting plans promise uptime, often 99.9%, with a service credit when they fall short. The credit is usually not automatic: you count the downtime and ask within a set number of days. The Uptime Reckoner does the counting, applies your agreement's own credit table, and writes the claim.

No account. No email. Nothing stored until you save. Uptime Reckoner sells no hosting and never watches your site: you type what went down.

Read it like a timetable
Every day of the month, midnight to midnight
Each row is a day. Red is downtime the agreement counts. Hatched is time it lets the host leave out, like announced maintenance. A blip shorter than the agreement's minimum shows in outline and counts for nothing.
An outage that runs past midnight on the last day is split, so each month is charged only its own minutes.
Three stops
From "the site was down again" to a credit on your bill
- 01
Copy the promise
Promised uptime, monthly fee, the credit table, the minimum outage, what is excluded and how many days you have to claim. It is all in the SLA page your host publishes.
- 02
List what went down
One line per outage, from your monitor's alerts, the host's status page or your own notes. Overlaps are merged, so no minute is counted twice.
- 03
Claim before the window shuts
Month by month: uptime to four decimals, the credit row it lands in, the dollar amount and the last day to ask. Then copy the claim into a ticket.

What "three nines" really allows
A percent sounds strict until it is turned into minutes. This is how much downtime each promise allows in a 30-day month before any credit is due.
