I've noticed in the past few days downloads from Cloudfront (Amazon's CDN) have become very slow - testing from two different Bigpipe Gigabit UFB connections, both in Auckland. I haven't had speed issues with Cloudfront before now, it's always been very fast.

 

An example file you can download is https://download.docker.com/linux/ubuntu/dists/xenial/pool/stable/amd64/docker-ce_17.06.2~ce-0~ubuntu_amd64.deb - I've been seeing speeds of ~20KB/s on that download, whereas cloudfront previously would get close to line speed. I'm also seeing slow performance on other files hosted on cloudfront, for example https://web.kamihq.com/web/notablecompiled/2.0.8993-20170908152259/notable.js , or you can do a online test at https://cloudharmony.com/speedtest-for-aws:cloudfront 

 

Here's what one of these slow downloads looks like:

 

wget "https://download.docker.com/linux/ubuntu/dists/xenial/pool/stable/amd64/docker-ce_17.06.2~ce-0~ubuntu_amd64.deb"
--2017-09-10 13:06:26-- https://download.docker.com/linux/ubuntu/dists/xenial/pool/stable/amd64/docker-ce_17.06.2~ce-0~ubuntu_amd64.deb

And a traceroute:

If I ping, I'm seeing ~30% packet loss:

Anybody else seeing these speed issues? It could show up as a whole lot of different sites being weirdly slow, Cloudfront's used by a lot of different companies.

For what it's worth, that first link (Docker) took about 6 seconds to download on my non-BigPipe connection. Just to confirm that the problem isn't at Cloudflare's end.

Ah, I didn't think to check the Spark forum, egg on my face!

 

Though if any bigpipe people are reading I might humbly suggest that this is where updating the network status page ( http://pages.bigpipe.co.nz/network-status/ ) may be helpful :p

it would be nice if both spark and bigpipe updated their status pages - it will probably affect a large number of customers even if the customers haven't realized it yet.

 

 

It's been known about since yesterday so no excuse really

being that this appears to be upstream of any spark entity and actually on the return route, it is a little more complex than just "we have an outage"

Yep related to this (I too are on BigPipe but this isn't a BigPipe issue in such): https://www.geekzone.co.nz/forums.asp?forumid=39&topicid=223043

 

I'll lock this discussion - best to discuss it over there as staff from both BigPipe and Spark are watching it.
