Unable to download data from the 30-Meter SRTM Tile Downloader

by edwardsch » Mon Aug 15, 2022 10:44 am America/New_York

I'm trying to grab data from https://dwtkns.com/srtm30m/ and have never been able to get the download to work. I always receive the error "e4ftl01.cr.usgs.gov refused to connect." on both my personal computer and my work computer. Does anyone know what could be causing this issue?

Thank you for reaching out with your inquiry. The data center that hosts the dataset of interest that you attempted to download is currently experiencing downtime due to an issue that is under investigation. The LP DAAC has been experiencing high volumes of user traffic. This has been impacting data downloads for some users and causing timeouts. We have been implementing fixes for this issue. Please try to clear your cache one more time and access the data again. We have found that things are spiking upward again now, but these tend to relate to times users begin their day. You might want to try during off busy hours for best chance of success.
We apologize for the inconvenience. If you continue to have download issues, please contact LPDAAC@usgs.gov

Thanks for the response - I have tried clearing my cache and accessing the data during off busy hours with no luck. Given the known issues, I'll give it a few weeks before reaching out to the email provided. Thank you!

Hi @edwardsch
The LP DAAC has a scheduled maintenance August 17, 2022 that hopes to deliver a new fix which appears to handle some known bugs potentially causing our problems. Until then we'll be bouncing our servers hourly and cleaning up all hung CLOSE_WAIT sessions in order to keep data moving as best we can. Please keep trying to download the SRTM data.

Hi @edwardsch The LP DAAC has completed the planned maintenance Jan referenced earlier. We believe users should see improved data access now. Please try your request again.

@edwardsch ,

Have you tried from another browser? Even after clearing my cache in Chrome is still get an error, but when I try from Firefox I'm able to download the tile.

I've been trying to download the data with Chrome and Microsoft Edge. I downloaded Firefox to try it out and got the following error:

"Unable to connect

Firefox can’t establish a connection to the server at e4ftl01.cr.usgs.gov."

So no luck, I'm afraid.

Hi @edwardsch We are still experiencing issues and looking into other solutions. At this time the best advice I have received is to try and download data half an hour after the top of the hour (i.e. 1:30, 2:30, 3:30, etc) as this is when we are manually refreshing connections until we have a better solution. Apologies for the delay, thank you for your patience while we work through this.
