I have been fetching data from a url for years. Last week, it stopped
working, yielding nothing but DeadlineExceededError after 15 seconds (which
I have set for the timeout)
>From the destination logs, it appears the fetches are not reaching the
destination server.
The fetches work from my development machine, in 2 seconds flat. The URL
is fine, as I can hit it easily. Other urls fetch properly. It is just
from this destination server that there are problems.
Something in the production environment is blocking the fetch.
How can I possibly diagnose this?
Here is my code:
def asynchronous_get(list_of_urls):
rpcs = []
for url in list_of_urls:
rpc = urlfetch.create_rpc(deadline=15)
urlfetch.make_fetch_call(rpc, url, allow_truncated=True)
rpcs.append(rpc)
fetch_list = [rpc.get_result() for rpc in rpcs]
return [rpc.get_result() for rpc in rpcs]
Using 1.8.6 in development, but 1.8.7 in production. This problem started
well after 1.8.7 was started.
Error log:
Traceback (most recent call last):

Thank you.
