Distance matrix api times out when previously working fine(?)

I have tried to locate a post for this issue, but can’t see one. I have a section of code in a file that calls the ORS distance matrix API. This has been unchanged and working fine for months. I ran this code this morning and it worked fine as normal (30-50 second run time). I’ve gone to run this exact same code this evening and it has timed out at 2mins 3-4 sections. Are there any known issues with the API that could be causing this?
The code I’m running is pasted below. combined_coords has a length of 494, made up of 491 source coordinates and 3 destination coordinates. I’m comfortably within my allowance on the dashboard too. The API response is 504 Gateway Time-Out. When reading through the traceback I get the error message " JSONDecodeError : Expecting value: line 1 column 1 (char 0)".
Many thanks in advance for confirming if there is a known issue with the API / any advice you can provide to help me resolve this issue as I’m fairly new to using json in python still. Thanks.

Hi @MREves,

probably due to some downtime of the driving-car server (see status).

If you encounter this issue during uptime, it would be good the know the specific request where it hangs on.

Best regards

Ah thanks for the quick reply and clarification. I hadn’t seen the status page, thanks for sharing the link. Will retain for future reference.
