No, almost certainly not.

A lot of news articles about Healthcare.gov have mentioned Jekyll, an open source tool for generating database-free websites.

I've asked people who know Jekyll well and the consensus is that the problems lie elsewhere.

Jekyll simply generates HTML files. Jekyll doesn't create slow database connections, put excessive load on the server or add too many external files. Jekyll was just a tool for the designers to use.

In other words, Healthcare.gov may have struggled for a variety of reasons from the database, the servers, bad management, bad workmanship, or excessive traffic, but none of these were the fault of Jekyll.

This Slate article seems to pinpoint connections to the Oracle database as a primary source of errors. This article produces a screenshot of problems related to Oracle Access manager.
