Geo-redundent fallback for PTV xServer API Version 2
Our PTV xServer cluster with API Version 2 is designed with geo-redundency. That means that there are equal systems hosted in Europe and in the US. Even if a complete PTV xServer data center would go down, the requests will be automatically routed to a data center in another region, when using the routed URL.
Stateful tasks are functions that involve multiple requests that need all to be executed on the same data center. For PTV xServer internet these are job requests (start/fetchCalculateTour) and all xTour-request, as xTour needs pre-calculated distance matrices that are re-used throughout multiple requests.
You can set the data center URL within you application. In case of an outage or incident on your current data center you can temporarily change the data center to maintain productive operation.
