So it is 6 hours complete outage in around 22 months since its opening beta. The lifetime outage is somewhat around 6/(30 * 22 * 24) = 0.00037 = 0.037%! I think

So it is 6 hours complete outage in around 22 months since its opening beta. The lifetime outage is somewhat around 6/(30 * 22 * 24) = 0.00037 = 0.037%! I think this is pretty impressive achievement to build a system with uptime as 99.963%. Especially for some poor engineers woke up at 2am in Seattle and started to figure out what went wrong and get it back on line. I think it is pretty cool.
In the case when our PCs/Macs crashed. Even I could rush to a Circuit city/JR store to get a replacement hard drive. I probably will spend the same amount of time just to revive my system, given I have good habit back up the system. If that is not the case, I will need to reinstall operating system and applications. I guess the down time may be 24 to 48 hours.
So the downtime for a person without good habit in backup. The uptime will be 99.849%! if it takes 24 hours to get back the system in 22 months.
- boredguy8 19y ago3 9's uptime as "pretty impressive"? You must be a programmer.
- eugenejen 19y agoYes. as a lousy programmer and lousy administrator myself, I am pretty impressed at 3 9's for a new system that support HTTP DELETE, PUT under heavy load can reach such record. I am too ignorant to know any WEBDAV based system can be that reliable under the same load. And I am also amazed that the downtime for my PCs/Macs is far inferior than an immature s3! And I am also wondering the day those systems can be as reliable as telecom's 5 9's (5 minutes/year).
- trevelyan 19y agoWe use them commercially too, and I am very happy. For a system that is under development (and presumably iterating internally), support has been nothing short of fantastic.
