Linked Data Calls Fail - Timeout?

Hi,
 
Thank you for providing OpenCalais.
 
I'm having problems accessing linked data. My calls to linked data URLs (with .json extension) frequently return empty response. Response time of such empty responses is almost always 60 seconds. It looks like there is a timeout limit somewhere.
 
I'm using PHP with cURL calls. I've set cURL timeout to 120 seconds to make sure cURL doesn't cause a timeout. PHP is running localy and has no execution time limit.
 
If I request the same linked data url in a browser I get the correct data (example: http://d.opencalais.com/er/company/ralg-tr1r/47c6db7f-7989-3285-b453-2a7e2606d764.json). Browser request sometimes takes a long time but it doesn't timeout.
 
Is there something I can do on my side?

I've collected some statistics. 4% of linked data URLs take longer than 60 seconds and usually return an empty response.

I obey API limits and use the same limits (max 4 calls per second) for linked data calls.

Does anybody have an idea why so many linked data calls are so slow?
