Slow download speeds from dl.fedoraproject.org

Hello, I've noticed our rsyncs of fedora sometimes end up crawling along at around 50-150kB/s. When there's a lot of content to mirror, this means the sync could take several days, or even a week - although I'd imagine the remote end would terminate the connection long before that. In normal circumstances, we'd get anything between 5-10MB/s from dl.fedoraproject.org. I was thinking that a particular host in pool of servers was having an issue, so I did an rsync from it directly, however the speed was normal: rsync -Pav \ 209.132.181.26::fedora-buffet0/fedora/linux/releases/24/Workstation/x86_64/iso/Fedora-Workstation-netinst-x86_64-24-1.2.iso . ---8<--- receiving incremental file list Fedora-Workstation-netinst-x86_64-24-1.2.iso 460324864 100% 6.61MB/s 0:01:06 (xfer#1, to-check=0/1) sent 55 bytes received 460381543 bytes 6720899.24 bytes/sec total size is 460324864 speedup is 1.00 These slow downs only seem to occur when we use dl.fedoraproject.org, if we switch to another host such as download-i2.fedoraproject.org, for example, it remains stable. dl.fedoraproject.org is around 150ms away from us (connecting from Dublin, Ireland), but I wouldn't imagine this would cause such drastic speed drops. rg -- Rob Gallagher | Public Key: 0x841386E3 HEAnet Limited, Ireland's Education and Research Network 1st Floor, 5 George's Dock, IFSC, Dublin D01 X8N7 Registered in Ireland, no 275301 ☎ (+353-1) 6609040 WWW: http://www.heanet.ie/
