After Google crashed, two days ago, today, I noticed Gmail kept bouncing back my emails today with "address not found" - and some emails sent were never received.
I didn't even know about the lost ones, because there were no bouncebacks, until my boss texted me, asking if I got something she sent (which I didn't), and vice versa - she also hadn't received something I'd sent, with no bounce-back.
We received some bounce-back on some things, nothing at all on others, so we began texting after each send to be sure.
I just did a little search online, and apparently, we aren't the only ones - from Business Insider.
This also apparently affects Microsoft email accounts that integrate with Google products (like my husband's, which explains my husband's work email issues today).
So if anyone sent me an email today and I don't reply, I'm not ignoring you, I just didn't receive it. Text me and/or try again tomorrow- thank you!
