In a recent post, we talked about how stable and reliable Amazon AWS services were. This is a quick note to illustrate this in hard numbers:
- 53 live web-sites
- 39,432 live hours during October
- 9hrs of downtime, 99.9998% uptime
- 71 outages, 58 from the bottom 10 servers
- 6 of the worst 10 are hosted on dedicated servers
- 1 is an AWS server, with 7m of downtime
- 3 of them are applications servers for internal functions so don’t count
- One server, with 26 outages, is a Windows Hosted Server (Yuk!) that can’t seem to stay up for more than a day
Still hosting on a dedicated server? Why?
Post note: 4 of the client sites on this list will have moved over to cloud-based services before the end of January – one notable exception (ahem, 26 outages?) is simply upgrading the service to a bigger Windows box. Doh!
