I ran into this once when using a download url for the usgs service:

requests.exceptions.HTTPError: 503 Server Error: Service Temporarily
Unavailable

Are there limits on the number of download urls I should be fetching at
once?  Is this a common problem?

I haven't run enough at once to know if this is going to be a broader
problem, but if so it will mean I need to reconsider my approach which can
result in quite a few parallel downloads.

Best regards,
</pre>

    Hi Frank,<br>
    <br>
    After searching around for a download script, I found those two
    options:<br>

    <br>
    Are you using one of those or is there another solution to the
    download problem?<br>
    <br>
