The Google Multi-Datacenter rank checker was offline for about the past 10 days due to a couple of issues, one of which was the structure of the table I am using to store the search history. As a workaround I made a blank copy of the table and archived all of the old data. Within the next week I hope to restructure how I am storing things and port the old data over to the new tables. The tool should work fine in the interim, please let me know if anyone notices any new issues.
Thank you Donna for prompting me to fix it. 😀
