I was doing a yum upgrade on DigitalOcean, this was about 100k/sec.
So I decided to download an iso from my laptop (comcast business) and initially got 3.5MB/sec, but it quickly was reduced to 200k/sec.
I think some kind of throttling is going on.

This is from Digital Ocean "San Francisco 1". Subnet is 107.170.227.0/24.
My download starts off at about 20MB/sec and is quickly slowed down to about 10k/sec for about 2mins, then it slowly gets back to about 5MB/sec (just doing a liveCD iso download). I'm also opening up tickets with the Digital Ocean guys - maybe they are doing something?
Previously I had my own centos mirror in several co-lo's, but funding issues are causing us to shutdown our co-lo's and switch to hosted. Maintaining our own mirror is no longer in the budget. When I had my own mirror I never experienced any slowdown at all - even when pulling across co-lo's (mirror was not public).
My other theory is disk IO on your mirror might be slow - so unless I'm hitting hot files that are cached I get bad IO. Example: doing a "yum groupinstall Additional Development" is particularly bad if gatech mirror happens to get picked.

I know you are quite a distance away but if you wanted to try our mirror for reference please do – centos.mirror.nexicom.net
We have several folks in San Francisco area using this mirror and getting reasonable speeds (considering distance)

For comparison, I tried pulling http://www.gtlib.gatech.edu/pub/centos/6.5/os/i386/images/install.img
From the University of Utah (via Internet2), I got 25 mbyte/sec (both via
ipv4 and ipv6).
From CenturyLink, I got 2 mbyte/sec (on a 40mbit DSL line).
Feel free to try hitting mirror.chpc.utah.edu and see if that does better for you.
Thanks, DR
