No E911 info was erased.

There was a short time where it was temporarily not viewable due to planned upstream maintenance (not on our end) on the part of the upstream E911 provider, but it was still there and calls would route accordingly.

We don't store E911 info locally. It's all viewed and stored directly with the third-party E911 provider so there's never a case of it being out of sync. When they conduct maintenance, that means when we query them for the address on file, it wouldn't show up.
