Anybody noticed that imgur images appear to be very very slow the last couple days?
Example: https://i.imgur.com/LXr9Prx.jpg (or without SSL)

Now here's the weird bit...

$ traceroute i.imgur.com
traceroute to i.imgur.com (103.245.222.193), 30 hops max, 60 byte packets
1 192.168.10.1 (192.168.10.1) 0.272 ms 0.275 ms 0.269 ms
2 * * *
3 218.101.61.101 (218.101.61.101) 16.874 ms 20.125 ms 17.820 ms
4 203.167.249.138 (203.167.249.138) 27.312 ms 27.341 ms 27.334 ms
5 203.167.249.139 (203.167.249.139) 27.422 ms 27.382 ms 27.412 ms
6 203.57.145.135 (203.57.145.135) 31.351 ms 23.814 ms 203.57.145.139 (203.57.145.139) 29.748 ms

13 * * *
14 * * *
15 * * *
16 * * *
17 * * *
18 * * *
19 * * *
20 * * *

And the super crazy weird bit

$ whois 203.57.145.139 | grep netname
netname: TRADEME

Whaaaaat?

Trademe performance is abysmal, half the posts in my Reddit app wont load (i.e. ones including imgur hosted content) Start the VPN and all is well though. You're not the only one experiencing this.

gbwelly: Trademe performance is abysmal,

The question is, why is imgur being routed through Trademe's network at all.

203.167.249.139 is part of AS4768 (Owner: CLIX-NZ TelstraClear Ltd,NZ) Not trademe, but part of vodafones network still.

Trademe (202.162.72.2) is AS9834 (Owner: TRADEME-AS-NZ Trade Me Limited,NZ)

i.imgur.com is ran on a fastly cdn (IIRC it used to be on aws) I would suspect the change of hosting providers is what your noticing..

Atlest on VF adsl, peering in auckland.

Tracing route to imgur.com [103.245.222.193]
over a maximum of 30 hops:

1 <1 ms <1 ms <1 ms pfsense.lanrouter [10.3.57.1]

9 44 ms 53 ms * 103.245.222.193
10 * * 26 ms 103.245.222.193

Trace complete.

Excuse the timing, connection is currently pegged out.

Simply put, its not on Trademes network at all.

hio77: 203.167.249.139 is part of AS4768 (Owner: CLIX-NZ TelstraClear Ltd,NZ) Not trademe, but part of vodafones network still.

Trademe (202.162.72.2) is part of AS9834 (Owner: TRADEME-AS-NZ Trade Me Limited,NZ)

Firstly, we are talking about i.imgur.com not imgur.com two different host names.

You will see in my traceroute I highlighted the last IP that responded,

It's neither of those.

The last IP that responded in the trace was 203.57.145.139 then the responses stopped.

As I posted, that net is owned by TRADEME according to whois data

My bad, just got home from work and didnt compare traces accurately when doing lookups.

Yes, 203.57.145.139 is part of AS9834 too.

203.167.249.139 vs 203.57.145.139 at a skim they look much alike!
Excuse my mistaken there.

As for where the content is actually hosted, You still do end up on the same endpoint.

https://imgur.com/blog/2013/06/04/tech-tuesday-our-technology-stack/ This is when imgur moved to aws

https://www.fastly.com/customers/imgur May 2014 they became a customer, with announcements going out March yeah.

Assuming this is still the case, it would explain why traffic is going over trademe for some.

Yes that would explain the routing then.

Still dog slow though.

Glad to see I'm not the only one, also on Vodafone cable 100/10, i.imgur content pretty much fails to load every time last couple of days.

edit: appears to be fixed now.

I am on Sprk VDSL and have also been having issues with i.imgur.com. Every few days images will start failing to load. The site loads fine, but the images don't. Funnily enough a phone reboot fixes it, or waiting for an unknown period of time.
