Re: OpenDAP not working
There was an issue over the weekend, but the server is back up. Please confirm that you are able to access your data.
Re: OpenDAP not working
Hello,
I also can't access opendap since a few days. On the website (https://oceandata.sci.gsfc.nasa.gov/opendap/) I have an error message on all the machines I have access to (joined screenshot). When I try a data request with xarray (pydap engine) on Python 3 I receive this error code :
HTTPError: 403 Forbidden

Any idea what it could be ?
Thx for your help

Re: OpenDAP not working
There was indeed a block in place. Access to opendap has been restored. Are you able to retrieve your data now?

Re: OpenDAP not working
Hi amscott,
The Opendap website and python queries work fine with my personal wifi or mobile hotspot, but not with my lab's wifi. This is not the same error:
the web page https://oceandata.sci.gsfc.nasa.gov/opendap/ tries to load for a minute, then my browser error page "Can't reach this page" appears.
In my code, I have an error of type "HTTPError: Timeout" (which looks very similar to the browser problem).
I'll check with IT to see if that's where the problem is, but it was working fine in the lab before the recent problems, so I'd rather ask you too.
Thanks again for your help

Re: OpenDAP not working
I have more information : it's not only OpenDaP that I can't access, but the whole Ocean Data website (oceancolor.sci.gsfc.nasa.gov). Other NASA websites such as www.earthdata.nasa.gov work fine. In the lab we don't have any specific protection or any firewall that could explain this issue.
I tried to track down the issue in the connection nodes with "tracert" command and here is the result :
Route determination to oceancolor.sci.gsfc.nasa.gov [169.154.128.44]
with a maximum of 30 jumps:
