When we were doing a general update of all websites, we added analytics for the whole system. However, I did not pass on the instruction to preserve local analytics; therefore, many instances of local code were overwritten This is entirely on me. You did not receive a heads-up because I assumed the change would be transparent.
If you lost your analytics, please go ahead and put it back in below the "Add Local Analytics" line. If you want a report covering your site (whether or not you had analytics previously), please send a note with the date range.
