Banks of Servers
Waze uses at least three different banks of servers. One for the USA and Canada at http://www.waze.com, one for Israel at http://www.waze.co.il/ and one for the rest of the world at http://world.waze.com . These can have problems independently of each other, so please specify which one you use when reporting any issues.
In theory when you go to http://www.waze.com it should automatically switch you to the correct server but this does not always work. This leads to confusions as Cartouche maps and Dashboard points do not show. So if you are outside the USA, Canada and Israel go directly to http://world.waze.com
