However, it reveals a network issue: +# downloading from `ftp://gcc.gnu.org/` from Travis (using passive mode) often leads to "Connection +# timed out" error, and even when the download completed, the file is usually corrupted. This causes +# nothing to be landed that day. +# +# We observed that the `gcc-4.8.5.tar.bz2` above can be downloaded successfully, so as a stability +# improvement we try to download from the HTTPS mirror instead. Turns out this uncovered the third +# bug: the host `gcc.gnu.org` and `cygwin.com` share the same IP, and the TLS certificate of the +# latter host is presented to `wget`!
