The only uptimes I'm concerned with are my own services that my own monitoring keeps on top of, this varies - if the monitoring page goes down for 10 seconds I'm not worried, if one leg of a smpte-2022-7 is down for a second that's fine, if it keeps going down for a second that's a concern, etc. If something I'm responsible goes down to the point that my stakeholders are complaining (which is something seriously wrong), they are not going to be happy with "oh the cloud was down, not my fault" If AWS is down or not it meaningless to me, if my service running on AWS is down or not is the key metric. If a service is down and I can't get into it, then chatter on things like outages mailing list, or HN, will let me know if it's yet another cloud failure, or if it's something that's affecting my machine only.
