I don't complain too loudly because it's a free (and very useful) service, but I am wondering if we should not upgrade to something a bit more reliable.<br>

<br>
</span>My understanding is that the paid Travis service doesn't entirely help with the existing issues, which are infrastructure overload on their part. The paid service increases the number of parallel builds, but still (e.g.) enforces the per-job 50 minute limit.<br>
<br>
I'll prioritise the Rackspace VM work to let us unlock more builds. We're seeing an increasing number of repository failures due to the lack of reverse-transitive checking of builds, and that should be very easy to do in parallel on VM infrastructure.<br>
<br>
(I may be wrong about the latest in paid Travis -- if anyone wants to enquire with them, please do let me know. I'm happy to pay for the service if it would solve any problems.)<br>
