The "OSM Standard tile layer" looks wrong (white lines, abusive comments etc.)

Looks like somebody managed to hack the OSM Standard layer in the tile display and streak the map with long residential ways. It appears only that layer was hacked, not the actual database, as the damage does not appear on other tile layers nor do the objects appear when editing the database. This is seen in the area of Milford, Massachusetts USA. Please relay this to whom it may concern if possible.

On further review, the damage appears across a much larger area, possibly the entire map.

Other consumers generally only refresh their data so often, and a lot of those changes have already been reverted by mappers and the DWG. The standard layer will likely be back to normal once those tiles are requested and regenerated again.

Nothing was “hacked”. Some vandal just changed road names.
If you tell the exact location, it can be easily reverted and vandal flagged for ban.

Yes, it appears whatever that was has been reverted.

At least 3 vandal accounts have been banned. (And bunch of people reverting their vandalism). So just hang tight and map tiles will generate with all that garbage removed.

You see here an explain.
How can it be solved?

If the underlaying data is fixed (I believe it’s all been reverted), they’ll re-render soon, once someone has viewed the tile.

I’ve been called worse :slight_smile:

What I suspect might have happened is that following a series of complaints to the DWG, I reverted a large number of mechanical edits yesterday. The mapper concerned didn’t appreciate this, and sent various messages to me immediately after that block and revert. The “new account” performing this vandalism then appeared immediately afterwards. This may of course be a coincidence, but it’s not the first time that this particular scenario has played out with this individual.

The bad news is that they’ll probably try again with another “new account” from another throwaway provider. The good news is that, as here, it’ll all get reverted pretty quickly, and limits on the creation of “new accounts” and what new accounts can do is more limited than previously to prevent damage.

Edit: Actually there are at least 3 accounts (blocked); as noted above I’m sure we’ll see more.

I think the underlaying problem should be fixed, i just saw that these tiles are still junked…

Only to be sure that this is also fixed.

Thank you so much for your work!

The DWG have had a number of reports about this vandalism (as you’d expect). In most (at the time of writing, probably all) cases, it has already been reverted**.

However, if you see something on a rendered map such as at https://www.openstreetmap.org you’ll want to check that the problem has actually been fixed. In order to do that, go to https://www.openstreetmap.org and zoom right in to where there was a problem. Use the “?” button at osm.org and click on the map where the problem was. A list of “nearby features” will appear. If one of them looks wrong, please tell the DWG about it. If nothing looks wrong any more, then the data has been fixed and you don’t need to report it.

However, once the data is fixed, various maps and applications based on OSM data will still take time to get updated. If you think that a map or app displays incorrect data, please raise that issue with whoever is responsible for that map or app. If you are unsure how to contact whoever it is, then asking a question in the forum here is a good place to start.

** Edit: Some relations may still have some issues (at first glance this may be due to people trying to do reverts using buggy software), but the scale of the problem should be manageable. I’ll update here later.

Edit: I was only able to find one problem relation that needed fixing, and that’s now fixed. Another DWG member found one other. If there are more, please email data@openstreetmap.org to let the DWG know.

Another edit (9 days later) someone reported one more broken relation to us yesterday.

Even after the reverts the defamations remain in the data base (history). Are there plans to redact these changes, too?

Browser cache - OpenStreetMap Wiki has info how to request fresh tiles, which typically helps if vandalism was reverted already

I’m seeing posts on Mastodon about this issue. Really bad that there are people out there wanting to make fuss in public so hard against specific people…if those vandals read these comments, I hope you realize that you aren’t doing anything notable with these extreme actions, it just makes you look like the loser, and not the one you fighting against for.

@SomeoneElse Thank you for your support!

I noticed that the tiles that still show the wrong data are loaded from cache: See X-Cache HIT and expiry date of 17 of april in the attached screenshot. This would mean that some users will see the wrong tiles until the 17th of april.

We’ve tried clearing all the browser caches, also tried using different browsers and different computers. The wrong tiles seem to show or not depending on the location. Therefor I understand this is not browser cache but CDN cache issue.

Is there any chance the CDN cache can be invalidated sooner?

Maybe it’s worth considering some kind of manual invalidation of cdn cache when these things happen.?

Thank you!

That would be an issue for the OWG, not the DWG and SomeoneElse.

@Firefishy we summon you here to collect all reports on stale Fastly cdn caches that show vandalised tiles.

But on the technical side I assume that odin (the tileserver mostly serving tiles to the caches here in the Netherlands and Germany) is overloaded, see e.g. queue length of odin and ysera here: Grafana that shows a queue length of >8000 and dropped tile requests/sec >150 for both). E.g. I’m seeing the vandalism on zoom 14 and 15 in the Rotterdam harbor, but not on zoom 13. @pnorman maybe it is a good time to look into Shift more Europe traffic to newer machines · Issue #1030 · openstreetmap/operations · GitHub again?

Our cache invalidation is not perfect. There are edge cases where some things get missed.

Low zooms are force re-rendered overnight to fix some of the invalidation misses.
