“No news is good news” in the DDoS mitigation game, and this is what we were hoping for in August 2016. We decided to capitalize on this opportunity and focus the team on new developments supporting free Let’s Encrypt certificates for all Deflect clients, as part of the TLS/HTTPS system.
Then, on the 29th everything changed, as one of our oldest clients, Ferghana News, was the first media to report on the death of the president of Uzbekistan, several days before the official announcement. The bottom line is that Deflect’s statistics for August 2016 show what happens when no important DDoS attack hits our edges and at the same time some of the websites we protect get a lot of traffic from human visitors who are interested in news they have published.
In comparison with the previous month, in August we recorded a decrease in our total metrics, falling even below the figures we saw in the uneventful month of June, but at the end of the month we experienced a sudden peak, that made our monthly statistics bounce back to the latest trends. Overall, Deflect served 474 million pages to 7,7 million visitors. Meanwhile Banjax, our banning system, banned 20,294 unique IPs.
Dividing Deflect hits by requested websites, we can see that a large part of this increase is connected to Ferghana News, one of the most popular news outlets dealing with Central Asian countries, which was reporting about the death of the president of Uzbekistan in those same days.
Analysing this peak of connections by country of origin, it appears clear that the news published on Ferghana News attracted a lot of attention from Central Asian countries, including Uzbekistan, where actually the website is blocked for common citizens (but apparently not for government officers and powerful people). This is a common occurrence in censoring countries, where citizens are stopped from accessing information but rulers know very well how much value can be brought by an open internet.
Finally, here’s our monthly pie chart on our visitors’ operating systems. Fortunately, the usage of Windows XP keeps falling (7.58% against 8.13% last month), but overall statistics on the operating systems used by our visitors are unchanged, with about half the connections originating from a Windows system, a quarter from Android devices, less than 10% from iOS devices and just a tiny fraction of users choosing Linux or even Mac.
August attacks on the Deflect network
In August, Deflect didn’t experience any noteworthy attacks on its network, and all DDoS attempts were mitigated automatically.
Even at their peaks, the attempts at attacking websites protected by Deflect didn’t involve more than a couple thousand bots, and from their most common user agents and from the elements triggering our banning system, we can conclude that the most common method used these days to launch DDoS attacks is the WordPress Pingback reflective attack, which we have been describing in each one of our reports in the last few months.
