On the Login screen, you can select the server you want to access. Castor has a separate database within the stand-alone regions. Our US server is in the Americas (US) region while our NL and UK servers are in the European (EU) region. This means that if you need access to studies in more than one region (EU and US), you need an account in each region.
Study A is on the Netherlands server, meaning that all users, irrespective of location, have to select 'Netherlands (data.castoredc.com)' when logging in.
Study B is stored on the US Server meaning that all users must select 'United States (us.castoredc.com)' when logging in.
‘My Studies’ overview only shows studies created on servers within the same region. If you have access to studies in different regions, you have to log into the correct region to access the studies.
Selecting a server for a new study
If you want to start a new study on a different server than your current studies, you need to have an account on the that server as well.
Here are the URLs for each server:
https://data.castoredc.com/ means that you are logged in and will be creating the study on the server located in the Netherlands
https://uk.castoredc.com/ corresponds to the server in the United Kingdom
https://us.castoredc.com/ corresponds to the server in the United States
Please Note: The servers follow daylight savings from the region they're configured for. The Netherlands servers follow Amsterdam time (CET), UK servers follow London time (BDT), and the US servers, follow New York time (EST).
