The day Google (almost) lost my timeline data…

On the morning of 22nd March 2025 I received and read an email from Google giving me an “update” on my “Google Maps Timeline”, little did I know this was actually telling me they had just lost some of my data…

The email read…

We briefly experienced a technical issue that caused the deletion of Timeline data for some people. We’re reaching out as your account may have been impacted.
If you have encrypted backups enabled, you may be able to restore your data. Make sure that you have the latest version of Google Maps, then go to your Timeline. Tap the cloud icon near the top of your screen, and choose a backup to import your data. If you did not have backups turned on, unfortunately you will not be able to recover lost data.
We understand that this can be frustrating if you use Timeline to remember places that you’ve visited, and we are taking steps to improve our systems for the future.

I have heard of Google loosing data before (drive files and or photos disappearing and such), or making it inaccessible for people, and so far I’m glad to not have been affected, and have never really dived into these cases before to see if it has happened.

However, it was easy to see in a matter of minutes that ~10 years of location data was indeed gone from my phone… With data only showing from the 6th or 7th of March.

Grafana, Graphite and maxDataPoints confusion for totals

The title is a little wordy, but I hope you get the gist. I just spent 10 minutes staring at some data on a Grafana dashboard, comparing it with some other data, and finding the numbers didn’t add up. Here is the story in case it catches you out.

The dashboard

The dashboard in question is the Wikidata Edits dashboard hosted on the Wikimedia Grafana instance that is public for all to see. The top of the dashboard features a panel that shows the total number of edits on Wikidata in the past 7 days. The rest of the dashboard breaks these edits down further, including another general edits panel on the left of the second row.

Myanmar coordinates on Wikidata by Lockal & Widar

This entry is part 2 of 17 in the series Wikidata Map

In a recent blog post I showed the amazing apparent effect that Wikimania’s location had on the coordinate location data in Mexico on Wikidata. A comment on the post by Finn Årup Nielsen pointed out a massive increase in data in the Myanmar (Burma). I had previously spotted this increase but chosen not to mention it in the post. But now after a quick look at some items and edit histories I have found who we have to thank!

The increase in geo coordinate information around the region can clearly be seen in the image above. As with the Mexico comparison this shows the difference between June and October 2015.

Impact of Wikimania Mexico 2015 on Wikidata

This entry is part 1 of 17 in the series Wikidata Map

Recently Wikidata celebrated its third birthday. For the occasion I ran the map generation script that I have talked about before again to see what had changed in the geo coordinate landscape of Wikidata! I found, well, Mexico blossomed! The image to the left is from June 2015, the right October 2015 and Wikimania was … Read more
