We are performing a data refresh over the coming days starting 6pm UK time today and therefore you can expect periods when the Open PHACTS API and other services may be unavailable.
This update is refreshing key data sources including ChEMBL 23 plus other changes.
We will send more details on new services after the switchover and we thank you for your support.
In the meantime please ask questions via our support system. http://support.openphacts.org/
