Is the nds.gwosc.org server down?

I am recieving the same error while fetching AUX channel data for O3a run through the gwpy’s Timeseries fetch function.

Error: no data received from nds.gwosc.org for [time segs]

I have tried different combinations of time segments, channels, internet providers and even laptops with no success.

Thank you for letting us know. Indeed, the server was down, but it seems to be OK now.

Thank you for the prompt update

It seems to be a recurrent issue, I am once again getting the same error.
I am trying to fetch all aux channel data for O3a run channel by channel, I hope that is not causing this.

Hi @Shan909 and @esocugalik ! Thank you for posting this. I will take a look at the NDS2 server. If you are trying to access a large amount of data, we recommend using OSDF instead. We have recently posted instructions for accessing these same data via OSDF. I would appreciate if you could try the new method, and send us any notes on if the instructions are easy to follow. OSDF is designed to work better for large data downloads than NDS2.

I restarted the NDS2 server and it seems to be working again. I am sorry for the problem.

Thank you for looking into this. I had tried using the pelican pipeline before but it seemed a bit less documented compared to nds.
I will try again but in the meantime is there a limit to the segments/channels per week/month for the nds to not get overloaded? I can just limit my fetch code to certain segments at a time.
Thanks again
