This morning, I saw a long test upload of mine had failed. It keeps failing on restart. It calls out to a tool called arkb, but fails with this:

Requesting: https://arweave.net:443/tx_anchor
Error: timeout of 100000ms exceeded

The error shows it is a simple GET request, and happens again when I run the process again. You can see the full error uploaded at https://arweave.net/bxVRcuA4AIDlVqV_Z5L2tW742TQkS4pwxVnw-FZotxA .

Meanwhile, if I do the request manually, it's working fine:

$ time curl https://arweave.net/tx_anchor
t4cNiM_h_U_6lA0DGq5qYSb-vGGp3L7B0K0L74M6f-4LfJNZP2sHfe_nB3M3bQFF
real 0m0.564s
user 0m0.024s
sys 0m0.011s

Similarly, uploading the error message worked fine. The failure only happens from a specific arkb upload, and presently is happening reliably.

It's frustrating that I see no immediate indication of why the error would occur, and would need to resort to a packet log to properly diagnose it. The call happens within a dependency library of arkb.
