Www.julialang.org: Download mirrors

[essenciary]

I noticed that downloading Julia is slow-ish, from Spain. It's probably the same for all non-US downloads. It's not critical but it would be nice to speed things up, I guess. Maybe a university could host the files somewhere in Europe, Asia, etc - if anybody can help with that? I can also take a look maybe there's a free CDN we could use? Might save on bandwidth costs as well, if that's a problem. Thoughts?

We are already using Fastly as the CDN.

[essenciary]

Ah, OK, then bandwidth is not a problem. So they don't have servers in Europe? My download comes through Seattle.

I see european servers on the cdn, but a lot of the traffic does seem to get served out of the US. That by itself should not necessarily be a problem. Can you have a few others try it out in Spain, perhaps through other ISPs?

@staticfloat may know better.

[staticfloat]

Hahahahahaha, okay this one gave me a good chuckle. I believe this is because our DNS entry for the fastly cache was set to the IP address that I looked up while in Seattle, but should instead be a CNAME that points to a fastly DNS entry that auto-selects. I've put in a request to have the DNS changed.

A NEWS item for Julia 1.0.3: Faster downloads!

[ViralBShah]

@staticfloat Did the DNS change get carried out?

[staticfloat]

DNS change has been carried out, give it an hour or two to propagate and this should be fixed. @essenciary can you verify that our julia*-s3 domains should be serving from global locations now?

[essenciary]

The traceroute is different and much faster so it looks like it worked
