( total minutes + small buffer ) / total minutes in interval
This means that if you have 30 minutes of network downtime on the first of the month, your reliability will be calculated as:
( 43200 - 30 + 10 ) / 43200 = 99.95%
Based on approximately 43200 minutes per month and a 10 minute buffer. We include the buffer because we do incur small single-minute uptime dings once in a while due to agent upgrades and such. It will take an entire month to regenerate back to 100% uptime given no further downtimes in the month, considering it it calculated based on a 30 days rolling window.
Machines with less than 98% reliability are automatically removed from the available GPU pool and can only be accessed by clients that already had their data on it.
