how to reverse 301 I created by mistake

I meant to do a temporary redirect, but was in a hurry – no sleep for 3 days working on this site…created a 301 redirect & now that I removed it (and also told Google console to re-index) the page is just blank.

Luckily I did not redirect the entire site – only the home page. I created another homepage here that works: myphd.stanford.edu/home.

Is there anything else we can do to get the 301 reverted quicker? Everyone will be going to myphd.stanford.edu because this is what we advertised.

Would creating a temporary 302 from myphd.stanford.edu to myphd.stanford.edu/home solve this problem? I’m at a loss.. thanks for your help in this urgent situation – we are presenting the url at a conference today & it is blank.
