Site Maintenance/Upgrade

I’ve noticed a problem with the site logo on the top, the image does not load. Opening the image in a new window navigates to https://fpc-discourse-backup.s3.dualstack.eu-west-1.amazonaws.com/original/1X/d958b2ac49ef38c873afd7a32fdb3668eed684bc.png

The HTTP request returns with 403 - Forbidden status code and the following body:

<Error>
    <Code>AccessDenied</Code>
    <Message>Access Denied</Message>
    <RequestId>8CD3126D214AF348</RequestId>
    <HostId>dJmT8hpCoOtk/NTX7XNKSL6lYPUVOlzwC7/rAD845+KTGH71pqWhvm7q52okO0zinvmZ51PDr1w=</HostId>
</Error>

Update: Other images are missing as well, see for example the posts in this thread: What are you using today? (I get the a similar 403 reply)

Also maybe some cache has been cleared as my avatar was a default image until I resynced mine from Gravatar on my profile page. I see that you @danielb have this default image too.
