@marcelina.barycka @konrad.sopala Can we get an update on the target date for multiple custom domains?
Looks like the feature is queued up for a beta release soon. From what I saw it would support up to 10000 custom domains.
do you have a link for where you found this information? it would be extremely useful as we are currently planning efforts to support this ourselves. Seeing it enter beta would change things dramatically 
Unfortunately, I do not have a link, I know this because we are part of the beta program now.

Dear all,
Yes, as @sarthak.sahoo noted in this thread, we are launching the Multiple Custom Domains capability. It is in Beta availability phase right now (on non-production tenants). This is planned to be followed by Limited Early Access (June end), and General Availability afterwards (September end). The public documentation will be updated accordingly.
It is possible to join the Beta program through this form (and we’ll share the necessary info): https://forms.gle/yiRYMYyKCiSmXrPL6
Thanks and regards,
Pawan

Hi team! 
This is a heads-up that we’re hosting an Ask Me Anything (AMA) session

to answer all your questions—from high-level strategy to specific technical implementation.
You can submit your questions from now until June 24 
, and we’ll provide detailed written answers during the live event.
If you have any questions about managing multiple brands 
, creating tailored login experiences 
, or simplifying your architecture with a single tenant 
, feel free to drop them in this thread. We look forward to your questions and seeing you there!
