All sites on the account are 403. I can login to FTP.
I'm not at work, and have not seen your ticket (or your message from DreamHost informing you about your disablement), so I'm just guessing here, but it seems to me they likely just set up an .htaccess file to forbid traffic until you can fix it.

How can you reduce the load if they do not let you login to wordpress and disable some plugins, get in some caching or reduce php calls or identify what the problem is. I will get PS if I need to, but such long downtimes are unacceptable.
"Logging in to WordPress" to disable plugins, or implement caching *after* the site has crippled a server is "too little, too late"; the time for *those* kind of fixes is *before* a server is hammered! Turning your site back on running WordPress *during* a crippling traffic spike will just subject other users on your server to more damage.

What I want is a response thereafter on how to fix the issue, or at least activate the site to let me fix the issue by optimizing the site or upgrade.
I cannot answer for the support staff on duty, and I don't have full access to the details of your circumstances. What, precisely, did they say when they informed you of the disablement? If you still have FTP access, and the site is disabled via an .htaccess file, have you considered just renaming your domain's web directory (that is holding the WordPress installation) to something else, and then creating a *NEW* directory for your domain and just placing a static HTML version of your page there till the traffic dies off? You could *then* re-enable your WordPress site and prepare properly for the next time (or make other arrangements like a PS server, etc.).
A "stumbleupon" wave of traffic should *not* cripple a static site ... just saying!
You could probably get a cached copy of the page from Google cache, or your own browser's cache, if you don't already have one, and place that there so your "post" still gets read (and add a note to it explaining it is a "temporary" site/post to keep your server alive until you can get things fixed). That way your visitors could still see the content they came for, and you could "survive" the rush!
