The Amazon issues did not, it seems, transmit through AZs, and not datacenters, this was me commenting a bit too early in teh morning. So yes, only one datacennter was affected, but multiple AZs were, and these are not so isolatied from easchother as one might think. The Datacenters seems to be though.<br /><br />Cheers<br />/KarlssonKarlssonhttps://www.blogger.com/profile/04874338187076980133noreply@blogger.comtag:blogger.com,1999:blog-9144505959002328789.post-982727853937772162011-04-25T11:59:41.901+02:002011-04-25T11:59:41.901+02:00Thanx Roland.

What I understand, it originally happened in one center, but that the effects actually migrated and affected some other centers.<br /><br /> I'lll sure read the article, seems interesting when we are to have a look at our options to fix this in the future.<br /><br />/KarlssonKarlssonhttps://www.blogger.com/profile/04874338187076980133noreply@blogger.comtag:blogger.com,1999:blog-9144505959002328789.post-16259973473765792162011-04-25T00:30:55.659+02:002011-04-25T00:30:55.659+02:00Hi Anders!
"I wonder how the other database ...Hi Anders!<br /><br />"I wonder how the other database HA Solutions for Amazon survived"<br /><br />apparently, one of Amazon's datacenters was affected. There is a very insightful article right here: <br /><a href="http://blogs.gartner.com/lydia_leong/2011/04/21/amazon-outage-and-the-auto-immune-vulnerabilities-of-resiliency/" rel="nofollow">http://blogs.gartner.com/lydia_leong/2011/04/21/amazon-outage-and-the-auto-immune-vulnerabilities-of-resiliency/</a> which suggests Amazon users could actually have shielded themselves from going down. Not sure how feasible that would be, but the article sure is worth a read.rpboumanhttps://www.blogger.com/profile/13365137747952711328noreply@blogger.comtag:blogger.com,1999:blog-9144505959002328789.post-79285969174878883952011-04-24T21:38:38.259+02:002011-04-24T21:38:38.259+02:00That's great!
