Inquiry about Cloud Run Domain Mapping in Europe North 1

[thamas05]

We are using Cloud Run domain mapping in the Europe North 1 region for our application. I understand that this feature is currently in limited availability and preview status (2025). I would like to confirm the following:
1. Is Cloud Run domain mapping still considered pre-GA and not suitable for production use in Europe North 1?
2. Does Google plan to support this service in Europe North1 in the future?

3. When it's planned for general availability (GA).

Hi @thamas05,

Welcome to Google Cloud Community!

To answer your question, as of 2025, Cloud Run domain mapping is still in Limited Availability (LA) and Preview status, which means it’s not yet considered fully production-ready across all regions due to latency issues. While the feature is functional, it may not yet meet all production requirements such as high availability or SLAs typically expected from fully GA services. It is also important to note that certain regions, including Europe North 1, might face specific limitations during this preview phase.

Google Cloud does plan to expand support for this feature to more regions as it progresses toward General Availability (GA). However, the exact timeline for GA has not been publicly confirmed yet.I would recommend keeping an eye on Google Cloud’s product documentation for the latest updates and to better understand any changes or improvements to the feature.

Hi, I'd like to provide a bit more clarity here. The biggest issue with custom domains in the regions where they are in preview is that the custom domains infrastructure adds quite a bit of latency to the requests. This is not likely to improve in the near term.

I'd suggesting trying out custom domains. If the latency is acceptable to you, go ahead and use them! If it is not, follow our instructions for setting up a custom domain through Google Cloud Load Balancing. This costs a little extra money but is GA and works very well. I see we also recommend a Firebase-based option.
