Hello!

I am trying to download the gas cell data from halos. For some halos it is working, but for some (z<0) I get the following error:

Code:
sub_prog_url = "http://www.illustris-project.org/api/Illustris-1/snapshots/128/halos/1128/"
sub_prog = get(sub_prog_url)

cutout_request = {'gas':'Coordinates,Masses'}
cutout = get(sub_prog_url+"cutout.hdf5", cutout_request)

Error:
Traceback (most recent call last):
File "image_404871.py", line 119, in
cutout = get(sub_prog_url+"cutout.hdf5", cutout_request)
File "image_404871.py", line 61, in get

Do you know why this problem appears and how I can solve it? It is strange, because for some halos it is working perfectly but not for all of them (but last week it was working).

Thank you and best wishes,
Moritz

Hi Moritz,

I would suggest you simply change illustris-project.org to tng-project.org in your scripts and API addresses. (The Illustris data is also available here, and using this address will request data from our more robust server at the moment).

Thank you very much! Now it is working!
