As we wrote on Friday, we tightened security around Atlas a notch, and before doing so we tested that the APIs were working as they should (since API accesses are something that easily get flagged by security systems) and everything looked fine. However, over the weekend several networks had their addresses fail to import.
The strange thing is that some networks managed to import a few addresses but far from all, which makes us believe that some call in the import process was still flagged and blocked. We haven't been able to figure out exactly what happened, but until we know, we are rolling back that change so we don't block anything more.
It might be a good idea to check the status of your Market Database if you use the API to update. You can see in the log Atlas CMSLog when it was updated and how many addresses it concerned, or in the statistics Atlas CMSMarknadsdatabasenFunktionerStatistik how many addresses you currently have in your database. If needed, run the update again to ensure everything is correct.
We apologize for this and will continue investigating what went wrong.
