Disappointedly lacking on details.
Why did page load time go up during the quake? Was there a fiber fault that took a few seconds to be routed around? Did the vibrations cause HDDs to temporarily suspend?
This could have some interesting data behind it, but as it is the article doesn't even have conclusive proof that the earthquake did cause this outage.
- acslater00 15y agoWell, I have no idea what actually happened down there, but the timing would be a pretty incredible coincidence.
- josegonzalez 15y agoAs far as the reason, you'd have to ask who works on AWS. For obvious reasons, we don't have direct access to the Amazon datacenter. As far as conclusive proof is concerned, yes, we can't guarantee there wasn't a gravitational singularity that affected response time, but it's very likely that this was the case.
- rhizome 15y agoSo, "AWS happened to it," then?
- BCM43 15y ago"Over here at SeatGeek, we were excitedly discussing the tremor when Mike, our trusty sysadmin, realized that our Amazon AWS servers were all in Virginia, right near the epicenter. Did it impact the service at all?"
- rhizome 15y agoI was reflecting on my parent's comment that the actual reasons were opaque due to SG's use of AWS.
- egiva 15y agoYeah, latency is most likely due to the vibrations affecting the various rack components, as commented here. Actually, earthquake-proofing datacenters is a big business in places like the West-Coast USA and Japan: http://www.datacenterknowledge.com/archives/2007/07/17/earthquake-proofing-the-data-center/ http://www.datacenterknowledge.com/archives/2007/07/17/earth...
- pistoriusp 15y agoI remember watching a video about how vibrations can have a negative impact on hard drive latency (Video is at the bottom.): http://blogs.oracle.com/brendan/entry/unusual_disk_latency http://blogs.oracle.com/brendan/entry/unusual_disk_latency
- jmmcd 15y agoPresumably the earthquake caused a spike in social network usage, microblogging of various popular types, and reload-mashing on cnn.com and similar. If any of those is hosted on AWS then they might steal some cycles from other AWS users.
- eli 15y agoPurely anecdotal, but here in downtown DC, cell networks were fine during and immediately after the quake, but were completely overwhelmed 5-10 minutes later by everyone pulling out their phone at once.
- heliodor 15y agoAnother thing that comes to mind is that some computers have accelerometers in them that stop the harddisks if the machine experiences sudden acceleration. If AWS has the same system in place, that might affect their servers' responsiveness.

- josegonzalez 15y agoYeah dude! These things happen.
