FYI to S3 customers, per the SLA, most of us are eligible for a 10% credit for this billing period. But the burden is on the customer to provide incident logs and file a support ticket requesting said credit (it must be really challenging to programmatically identify outage coverage across customers /s)

- machbio 10y agothats for below 99.9% - they are at 99.997% .. you are never getting that 10% credit..
- christop 10y ago0.1% of 28 days is 40 minutes, so it seems likely to happen.
- machbio 10y agoI was calculating it for a year - maybe the availability applies to per billing cycle - you may be correct..
- joatmon-snoo 10y agoYou got your orders of magnitude wrong ;) 99.9964583 = 100 - 153/(30*24*60) 99.6458333 = 100 * (1 - 153/(30*24*60))
- machbio 10y agoI was calculating it for a year - maybe the availability applies to per billing cycle.. I am still not able to understand your math - mind explaining
- joatmon-snoo 10y agoYour numbers are still off for a year. 99.9997089 = 100 - 153/(365*24*60) 99.9708904 = 100 - 100*153/(365*24*60) The formula is 100% minus 100% times downtime/time in month/year. 153 is the number of minutes they were down going off the reported updates at https://status.aws.amazon.com/ https://status.aws.amazon.com/ - 11:35AM PST was when they fixed the status page, 2:08PM PST was when S3 was fully back online. (And 153 is underestimating it, because there were errors going on for long before they fixed the status page, but I don't have timestamps on that.)
- primitivesuave 10y agoThe 10% savings of ~$10 does not compare to time/potential business lost, but thanks for the tip :)
- mabbo 10y ago> potential business lost My startup's op team had a great discussion today because of this that basically boils down to "if we hit our sales goals, an incident like this a year from now would end our company". Looks like our plans to start prepping for multi-cloud support will be a higher priority.

- omni 10y ago> an incident like this a year from now would end our company I'm genuinely curious, what kind of business are you in that a four hour outage would end the company? High frequency trading or something?
- owenmarshall 10y agoI'd be willing to bet that the effort you put into a multi-cloud solution will be more expensive than you think, and far more brittle in the event of an emergency. It always is.
