Node app hangs on request call #118

I have a Node server app that, when fielding a request, makes a request of its own to get the HTML source for the page, which it then modifies and returns as a response to the HTTP call.

I've used this technique in other apps, without issue. But this app intermittently hangs when doing this.

I can easily do a workaround, but I thought I should try to find out if anyone has ideas what could be going wrong.

Here's the code in question.

function getServerHomePage (callback) {
	var whenstart = new Date ();
	request (config.urlServerHomePageSource, function (err, response, templatetext) {
		if (err) {
			console.log ("getServerHomePage: err.message == " + err.message);
			callback (err);
		else {
			console.log ("getServerHomePage: " + utils.secondsSince (whenstart) + " secs");
			var pagetable = {
				config: configToJsonText (),
				version: myVersion
			var pagetext = utils.multipleReplaceAll (templatetext, pagetable, false, "[%", "%]");
			callback (undefined, pagetext);

When it hangs this is what the console.log call shows.

getServerHomePage: 106.97 secs

The server is running on Digital Ocean, the file its accessing is on Amazon S3.

I went ahead and worked around the problem, reading the template from a file in the local file system.
