I have been unable to access the WDS catalog data files for the past few weeks.  Keep getting a "resource not found" error.  Anyone know what's up?

For me it has been hit or miss--some days some of the WDS-affiliatated sites work and others don't.  Within the past 48 hours it appears to be a complete disconnection.

 

I hope it is just maintenance and not a funding issue.  I am also very curious to know what is going on.

I just used Stella Doppie.  Worked for me.

Stelle Doppie is the best workaround. The USNO site seems to have problems fairly often. Hackers perhaps?

That's why Georgia State University maintains a WDS mirror site, which always works when the USNO WDS doesn't.

That is great; thanks!

 

*Do you know if there is also a mirror for the 4th Interferometric Catalog?

 

EDIT:  I was able to access the data using the Way Back Machine

There's also a current copy of the WDS catalog on my Nexus DSC.

Download copies of the catalogs onto your computer. Sure, you don't get the gradual updates, but you have a reference set as of the download date that will cover most needs. I do this at roughly 6 month intervals so I don't have to rely on internet sites every time I want data. And the updates are mostly small in relation to the total over a short period such as 6 months.

 

I can always try for the current version online if there's a particular need, which isn't often the case given the recent (no more than 6 months' old) version being available.

Thanks to all for your replies.  Stelle Doppie has a pretty good search function.  GSU website is great.  Thanks for introducing me to these USNO alternatives.  Wish the WDS website would get its act together.
