Also getting this error from Github when trying to download the binary release for kube2pulumi:

<Error>
<Code>ServerBusy</Code>
<Message>Egress is over the account limit. RequestId:7acd46a7-b01e-006c-1c73-ebc9f2000000 Time:2021-12-07T14:08:08.9796530Z</Message>
</Error>

this looks to be an issue with GitHub itself, hopefully they update their status page

As a quick fix, you can try out https://www.pulumi.com/kube2pulumi/ for your kube2pulumi conversions

Wasn't working also, see the message above 😉
