My Tumblr is magically back from the land of the dead.
I was absent-mindedly clicking through all the links I normally open when I open a browser, and here it is back in all of its glory. No idea what happened, or how it was fixed but am grateful that it has returned.
Thank you to all of the Tumblr employees who replied to my emails about getting it back up and running.
YAY! And now, back to our regularly scheduled programming…
