We just switched to a paying plan after trying it for a week, and we just experienced some weird build timeouts / failures, which did not happen during our evaluation.
For example this build failed to restore nuget packages ( and some others timed out in performance tests (that usually work) (

Is there any issue at the moment on your infrastructure ?

    For nuget restore try adding -verbosity detailed to see actual error. There are sometimes intermittent issues on side - unfortunately, this is something we can't always easily fix from here. Use cache for NuGet packages:

    Regarding performance tests - I'm not sure about the reason of their failure without looking into them.

    Alright, I'll look into it more seriously if it continues.

    NuGet has been really unstable recently:

    When you do something locally it usually takes packages from your local cache, so you can't see most ongoing issues from there. On AppVeyor you test not only your code, but indirectly test all external services you depend on, like NuGet, npm, bower, even GitHub.

    I periodically clean NuGet cache on my dev machine (to verify customer issues) and I can confirm I experienced some lags today too - adding xunit 2.0 nuget packages to a new project took around 2 minutes! I guess VS, unlike nuget console, has either retry logic or greater timeout.

    To minimize your dependency from availability of external services we recommend using build cache (where applicable):

    I don't know what else to say to make you feel better. Maybe we should setup kind of monitoring for nuget and other services, if that helps...

    Ok, I reproduced the issue locally too, it was totally a issue,
    so I took your advice and enabled the build cache.

    Thank you for your quick support,
