Plugin completely broke and killed my site during the great S3 outage of ’17f

Hi all

So I haven’t even started investigating the exact cause of the issue, but during the great S3 outage which occurred on Feb 28 2017, my WordPress Multisite went completely down.

Error logs kept showing broken and empty headers being sent, and through some standard plugin deactivating trial and error, I discovered that once I disabled the amazon-web-services plugin my sites started working again.

Now, we are naturally also using the WP Offload S3 plugin in conjunction with this one and THAT could have been the cause (because that plugin relies on on this one)… but disabling this plugin is what worked.
