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!
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 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.
