Operation too slow. Less than 1000 bytes/sec transferred the last 30 seconds

Hi, my job http://jenkins.ovirt.org/job/ovirt-engine_3.6_check-patch-fc22-x86_64/119... fails with following line being printed in console: DEBUG util.py:377: http://proxy.phx.ovirt.org:5000/fedora/22/x86_64/repodata/repomd.xml: [Errno 12] Timeout on http://proxy.phx.ovirt.org:5000/fedora/22/x86_64/repodata/repomd.xml: (28, 'Operation too slow. Less than 1000 bytes/sec transferred the last 30 seconds') please, can someone look at it and find what's wrong? thanks, mar.
