I'm seeing this error in my reports:

An error occurred requesting list information from Mailchimp. "503: akamai_503 - "

This happens sometimes when loading a Signup form block, which is embedded in the page.

When we get it, the form fields all disable.

It seems like the error is a Mailchimp response to too many requests.

Are there any workarounds for this?

I haven't really investigated this, but it's possible that going to the Mailchimp lists settings will fix this - perhaps by updating some missing list cache? I.e.: /admin/config/services/mailchimp/lists

The errors stopped for me at the same time that I went there, but it could be a coincidence.

It's happened to me twice so far, it may have been triggered in a cache clearing event, perhaps sending too many requests too quickly.

This suggests that Akamai are blocking the requests and it's not entirely within Mailchimp's control:

I had the same issue and the solution of the commentary #2 worked for me.

I'm not sure how to try to reproduce this: it seems like there's a workaround if it pops up and perhaps that it doesn't pop up too often. Or, perhaps, we have some caching behavior that ought to change (either expiring, or caching more aggressively to avoid overloading Akamai).

@mariacha1 did you see this pop up again?
