[BUG] from sktime.datasets import load_UCR_UEA_dataset fails

[chihyeon-choi]

Describe the bug

We cannot load time-series datasets with 'load_UCR_UEA_dataset' function.

I encountered the following error:

gaierror Traceback (most recent call last)

To Reproduce

from sktime.datasets import load_UCR_UEA_dataset

x,y = load_UCR_UEA_dataset(name='Car', split='train', return_type='numpy3d')

Additional context

I think the 'load_UCR_UEA_dataset' function loads time-series datasets from the following URL:
https://www.timeseriesclassification.com/

However, I cannot access the page.

Is the error occurring due to a temporary problem with the URL?

Then, when can the URL problems be repaired?

If not, how can I load data with the 'load_UCR_UEA_dataset' function?

Because I derived some analysis results from the datasets with that function some months ago, I need to load datasets in the same way.

hm, seems like the website is down.

I would guess this is temporary? How long is this going on?
FYI, this is a third party location not maintained by sktime, we maintain only the loader.

In the past, it has also repeatedly broken - the location is not reliably maintained, for that reason we set up backup mirrors.

Now I thought it should try the backup mirror now, but it does not seem to get there, because the request times out with an URLError.
