To keep things in perspective - mainly so that the original commenter doesn't draw the wrong conclusions - most of the pageviews (28,876) occurred on the hosted blog, which is served by Posterous and not Freshdesk's Linode machine.
The other 10,000 or so pageviews presumably hit their Linode machine over the course of a day or two. There are 86,400 seconds in a day. On average, that gives their site 8 or more seconds to serve a single request. If your site cannot respond in 8 seconds, you will have trouble servicing any level of traffic.
This isn't comparable to being Slashdotted or TechCrunched. No need for elastic cloud servers in this case.
