These all failed at the start of jdk15 build pipeline, at exactly 23:30, could it be too many requests all at the same time?

Can you give the list of machines (or at least the jobs) that this is happening on?

Wondering if this is related? #1450 (comment)
As API forwards to the github API binaries URL

CC @johnoliver JIC this triggers any thinking with your investigation

NOTE: I've added the additional boot JDKs onto the zLinux build machines so those should no longer try to download. I suggest we make sure that is done universally. We can progress in AdoptOpenJDK/openjdk-api-v3#341

[andrew-m-leonard]

We've not seen this for a while now, any further api work can continue in AdoptOpenJDK/openjdk-api-v3#341
