Hello,
I have been using Apex to do an httprequest to a specific website. All it does is a form post to a page. I have found that about 10% of the time, it fails with a "System.CalloutException: Read timed out" error. I've been testing this in the developer console.
I also have access to a separate Salesforce org, and I have run the exact same tests from there, and it has never gotten the Read Timed Out error.

I even wrapped the request in a try statement, and it will re-attempt if it fails the first time, but the second attempt fails 100% of the time.

I am wondering why one Salesforce org would be experiencing the issue whereas another one doesn't. The one having issues is on na5.

The code I am testing with is as follows, but I have replaced the website URL as I don't really want to post it publically, but the page is very simple and typically returns instantly, even if you post garbage content.
 

    HttpRequest req = new HttpRequest(); 
	integer debug=0;
	Map<String,String> headers = new Map<String, String>{};
	headers.put('content-type','application/x-www-form-urlencoded');
	String method = 'POST';
	String body='cmd=test';
	req.setMethod(method);
	req.setTimeout(30000);
	if(method == 'POST') { 
		system.debug('content-type is >' +headers.get('content-type'));
		req.setHeader('content-type', headers.get('content-type') );

		req.setBody(body); 
		req.setCompressed(false); // otherwise we hit a limit of 32000
	}

	req.setEndpoint('http://WEBSITEURLHERE.COM/');

	if ( ! headers.isEmpty() ) { 
		for(string k:headers.keySet() ) { 
			system.debug('setheader ' + k + ' => ' +headers.get(k) ); 
			req.setHeader(k, headers.get(k) ); 
		}
	}

	Http http = new Http();
	HttpResponse res;

	String resultString;
	String resToString;
	String resBody;
	String resStatus;
	Integer resStatusCode=0;
     
	resultString='';
	try {
		res = http.send(req);
	} catch(System.CalloutException e) {
		system.debug('Error...will retry');
    		System.debug(e);
    		res = http.send(req);
	}
	resToString=res.toString();
	resBody=res.getBody();
	resStatusCode = res.getStatusCode();
	resStatus = res.getStatus();
	resultString = resBody;
	System.debug(resStatusCode) ;

Does anyone have any idea why a certain SF org might experience sporadic time outs?
Thanks for any help.
