For the last couple of hours I have noted extremely poor (slow, patchy) network performance to my Amazon EC2 instances, US-West N.California. Instances themselves are running totally fine by the look of it.

Anybody else noticing this?

Seems pretty inconsistent and dodgy here, Haven't tried these tests on a clean line though. (VF DSL)

@hio77 what's that testing tool? It looks really useful!

Cool test, but not sure I trust it. It's reporting 460ms latency to EC2 in US-West. I have an EC2 server in US-West and windows ping tells me I'm getting 160ms latency.

I agree on this too.

their CDN tests seem about right however..

It seems to have started going full tilt again now.

I noticed the routes changed slightly too forat least the instance I was looking at mainly.

Have opened ticket with VF about it and posted to AWS Support Forum also.

The route for us-west-1 as it leaves VF in San Jose seems to be unstable, as above, on one request it will work fine and on the next it will drag along at less than 10KB/s.

I spun up a test instance on us-west-2 and it seems fine (different route), it's just us-west-1.

Current results from that site...

Seems... seems... to be working better today, at least a few hundred KB/s up to a couple MB/s instead of a few KB/s. Given I'm only running against instances up to m3, that's probably within the realms of reason.

Hopefully this post hasn't jinxed it.
