I've been getting very slow downloads of Boost from SourceForge during my Travis builds for the past week or so. It goes as low as 40K/s:

Is anyone else having the same issue? It's causing many of my builds to time out.

I have noticed really slow download speeds as well. If you are just using the header-only libraries of boost, you could just download each module from github instead. Peter Dimov’s boostdep tool can tell you what modules are needed, and then you can download the tar file for each module from github directly with: https://github.com/boostorg/${module}/archive/${version}.tar.gz I have found this to be much faster than using sourceforge.
