You need to deploy them around the same time else contingency plans have it that everything just boots back up in another region, at least Google. us-east-1 otoh...

For now anyway you can use ublock to blow away:

• the promoted inane shit
• this fucker liked this inane thing
• et al

Use the picker to select the element for the promoted and step up until you find ="promoted" in the selector. This works for the other bullshit they try and shove down your throat and your feed will be 98% less shitty.
