GitHub recovers from major outage; cause unknown
GitHub, a frequent target of distributed denial of service (DDoS) attacks, experienced a major outage Tuesday morning; however, the software development hosting service tweeted shortly thereafter that it identified the problem and that its online operations were running normally again.
As of writing, it is not publicly known if the outage stemmed from an internal error or from the latest in a series of external cyber-attacks against the service. GitHub's site performance was noticeably impacted just this past 23 March following a DDoS assault against the website.
Asked for an update and an explanation of the underlying issue, a member of GitHub's communications department directed SCMagazine.com to its online status page, which showed that from around 4:30 a.m. to 6 a.m, eastern standard time, app server availability ostensibly plummeted to zero percent, while response times spiked.
Travis Smith, senior security research engineer at cyber-security software firm Tripwire, said in a statement emailed to SC, “while a drop in service such as this may be attributed to an operational malfunction internally at GitHub, it can't be ruled out that this was a targeted attack”, against not just GitHub, but also “any number of their customers who leverage GitHub's service in production environments.”
