Connection timeouts
Hi,
From approximately 22:30 UTC on 27 Oct until present we have been getting timeouts when trying to connect to the Dropbox API:
cURL error 7: Failed to connect to content.dropboxapi.com port 443: Connection timed out (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)
Traceroute to content.dropbox.com is as follows:

I have just received a reply from Digital Pacific explaining that:
"We erroneously blocked the IP due to suspicion of it being involved in a large attack on our networks, This error has now been corrected and the block reverted"
So this problem was with the host - my apologies for wasting your time. Thanks very much for your help.

Thanks for the report! We'll check on this. For reference, are you still seeing this now?
Hi Greg,
Yes - the connection still times out and the traceroute result is still the same as above.

Thanks! We're looking into this, but we haven't been able to find a network issue for that network route.
To try to narrow this down:
- Are there multiple users of your app, and if so, are multiple users affected, or just yourself?
- Which API endpoints in particular are you using, and which are affected?
- Is this affecting all of the attempts to connect to content.dropboxapi.com, or only some of them? If it's only some of them, about what percent are affected?
- Is there anything on your network connection, e.g., a proxy, firewall, anti-virus, etc. what may be interfering with HTTPS connections to content.dropboxapi.com?
- Can you share the information on https://dropbox-debug.com from an affected machine?
