SIA download not working in DATALAB python module

Question

Hi,

I am trying to download images with the SIA module in the datalab python package for the past 2-3 weeks. It never works even if I use the official example python notebook (https://github.com/noaodatalab/notebooks-latest/blob/master/04_HowTos/SiaService/How_to_use_the_Simple_Image_Access_service.ipynb).

This question was asked multiple times before and the solution was to try it later again. I wonder whether I do something utterly wrong or whether the technical problem still persists. Could you confirm that the image download tool is working at the moment? Is there a healthpage where we can see if this tool is working or not?

Cheers,

Steve

Hi, I have the same issue as Steve with the SIA service again today, with the same SIA tutorial notebook (and I get similar errors in my own NBs where I was attempting to search the sia/nsa and the sia/raw_all URLs). The last time I encountered this error the NOIRLab archive was also down, but today I was able to do an image search via the webform, so it maybe it's something specific to SIA?

DALServiceError: 502 Server Error: Proxy Error for url: https://datalab.noao.edu/sia/stripe82_nsa?POS=335.0%2C0.0&SIZE=0.1%2C0.1&FORMAT=ALL&INTERSECT=OVERLAPS&VERB=2

Hi, I'm also having this issue when I try this:

DEF_ACCESS_URL = "https://datalab.noao.edu/sia/ls_dr9" # ls_ds8
svc = sia.SIAService(DEF_ACCESS_URL)

svc.search(pos=(35.4089, -41.8450))

And then

DALServiceError: 502 Server Error: Proxy Error for url: https://datalab.noao.edu/sia/ls_dr8?POS=35.4089%2C-41.845&SIZE=0.0056%2C0.0056&FORMAT=ALL&INTERSECT=CENTER&VERB=2

Same as above, the SIA servers appear to be down.

I can confirm that the SIA notebook progresses further. BUT it's still not working for the LS DR7.

Hi Steve,

Have you tried using this:

DEF_ACCESS_URL = "https://datalab.noao.edu/sia/ls_dr7".

It does work for me.

When I change the address to ls_dr7, the query returns a list of hits. When I try to do the download I get this error message "HTTPError: HTTP Error 500: Internal Server Error".

(I checked that I am logged in.)

I confirm that issue for both DR7 and DR9, and DES DR2.
