Comments:
Hi,I also posted it to the forum, but this is a bug, perhaps it needs to be reported here? thanks 

It looks like the official OPUS server for WMT16 doesn't provide the data files anymore (503 error).
I searched a bit and couldn't find a mirror except maybe http://nlp.ffzg.hr/resources/corpora/setimes/ (the data are a cleaned version of the original ones though)
Should we consider replacing the old urls with these ones even though it's not the exact same data ?

The data storage is down at the moment. Sorry. Hopefully, it will come back soon. Apologies for the inconvenience ...

Dear great huggingface team, this is not working yet, I really appreciate some temporary fix on this, I need this for my project and this is time sensitive and I will be grateful for your help on this. 

We have reached out to the OPUS team which is currently working on making the data available again. Cc @jorgtied 

thank you @thomwolf  and HuggingFace team for the help. 

OPUS is still down - hopefully back tomorrow.

Hi, this is still down, I would be really grateful if you could ping them one more time. thank you so much. 

Hi
I am trying with multiple setting of wmt datasets and all failed so far, I need to have at least one dataset working for testing somecodes, and this is really time sensitive, I greatly appreciate letting me know of one translation datasets currently working. thanks 

It is still down, unfortunately. I'm sorry for that. It should come up again later today or tomorrow at the latest if no additional complications will happen.

Hi all, 
I pulled a request that fix this issue by replacing urls.

Thanks!


It's still down for the wmt.
