-**TensorFlow Hub has moved to [Kaggle Models](https://kaggle.com/models).**
-
-Starting November 15th 2023, links to [tfhub.dev](https://tfhub.dev) redirect to
-their counterparts on Kaggle Models. `tensorflow_hub` will continue to support
-downloading models that were initially uploaded to tfhub.dev via e.g.
-`hub.load("tfhub.dev/<publisher>/<model>/<version>")`. Although no migration or
-code rewrites are explicitly required, we recommend replacing tfhub.dev links
-with their Kaggle Models counterparts to improve code health and debuggability.
+**Warning: unmigrated tfhub.dev model artifacts will be deleted on March 18,
+2024.**
+
+As of November 15th 2023, most [tfhub.dev](https://tfhub.dev) URLs and model
+handles are now redirecting to their migrated/equivalent counterpart on Kaggle
+Models.
+
+On March 18, 2024, all unmigrated model assets previously surfaced on tfhub.dev
+will be deleted – after this date, `hub.load` and `hub.KerasLayer` calls to
+these tfhub.dev handles will fail permanently. See the list of unmigrated model
+assets here:

+**If you are an owner of an unmigrated model, please get in touch with us at
+[email protected] if you'd like to migrate your model. If you take no
+action, your model(s) will be deleted on March 18, 2024 and not retrievable
+(either by you or other users).**
+
+For models with a Kaggle Models copy, there will be no impact on the
+availability/functionality of models that were copied from tfhub.dev –
+`tensorflow_hub` will continue to support downloading models that were initially
+uploaded to tfhub.dev via
+e.g. `hub.load("https://tfhub.dev/<publisher>/<model>/<version>")`. To see if a
+tfhub.dev model has been migrated, enter the model handle in your URL bar – if
+the redirect is successful, it has already been migrated, otherwise it is an
+unmigrated model and will be subject to deletion.
+
+Although no migration or code rewrites are explicitly required, we recommend
+replacing tfhub.dev links with their Kaggle Models counterparts to improve code
+health and debuggability.
