Waze HQ have done some further work and would like to know if it's had any impact.

Please can you report below any further issues with routing in London, please specify the origin and destination and the day and time you tried. If you don't want to publicly state the addresses then please send me a private message.

I'm very into the investigative fault finding work, and am glad to see people with better skills sets than mine working within the community in their spare time!


Chris (twister) has done fantastic work on this as well as keeping various scripts up to date with numerous coding changes from Waze. Without his work the UK Waze map would be a lot less complete.

The results from last week have now been broken down into daily graphical summaries.

The two routes returned are graphed out as red = fastest and blue = shortest. Where the graphs have a yellow background, the server failed to return any routes. The horizontal axes are marked off in hours.

The "Route Time" and "Route Distance" graphs show the calculated times and distances for the returned routes.

The "Server Response Time" graph shows how long it took the server to respond to the routing request.

Maybe it's SnapChat routing - the route disappears before you've seen it! :lol:

It'll be an instagram interface so you can post your screenshots of the routing failing ...

We can but hope. We're still none the wiser as to what exactly is the problem. My money is still on some algorithm issue rather than pure server power.

One of these days I'll check the results and see the routing server hasn't fallen over at the start of the morning rush hour, but that day isn't today... Oh well, it'll all get fixed "soon", right.


I now have a full weeks-worth of data logged for this test route, and whilst a full summary/data upload will have to wait until I've got more free time than I had over breakfast this morning, the TL:DR version is both simple and unsurprising - the routing server performance appears to be no better now than during any of the previous test runs...
