A while ago (in the time of big-versus-small buffers brouhaha) I asked JR Rivers to do a short presentation focusing on buffering requirements of data center switches. He started by describing typical buffer architectures you might find in data center switches.
Telefónica is already testing the AppFormix Health Bot.
Cloudflare has been recognized as a leader in the “Forrester WaveTM: DDoS Mitigation Solutions, Q4 2017.”
The DDoS landscape continues to evolve. The increase in sophistication, frequency, and range of targets of DDoS attacks has placed greater demands on DDoS providers, many of which were evaluated in the report.
This year, Cloudflare received the highest scores possible in 15 criteria, including:
We believe that Cloudflare’s position as a leader in the report stems from the following:
An architecture designed to address high-volume attacks. This post written in October 2016 provides some insight into how Cloudflare’s architecture scales to meet the most advanced DDoS attacks differently than legacy scrubbing centers.
In September 2017, due to the size and effectiveness of our network, we announced the elimination of “surge pricing” commonly found in other DDoS vendors by offering unmetered mitigation. Regardless of what Cloudflare plan a customer is on—Free, Pro, Business, or Enterprise—we will never terminate a customer or charge more based on the size of an attack.
Because we protect over 7 Continue reading

We recently shared the first part of Vashkar Bhattacharjee’s story. Vashkar is the National Consultant, Accessibility, A2i, Prime Minister’s Office of Bangladesh, and the Program Manager, Young Power in Social Action (YPSA). Here is Part Two.
Setting up an accessible digital talking book system (DAISY) in Bangladesh
After training in Japan, I was armed with knowledge in leadership and technology and wanted to create digital access for people with disabilities in Bangladesh. I wanted to prove that people with disabilities like me can work in our job market, but nobody wanted to believe me. With Young People in Social Action (YPSA), a social development organization in my home district of Chittagong, I worked as a volunteer on creating computerized braille production, which allows for printing to be in done in Braille, thus creating the tools for education for people with visual impairment. Very soon, we obtained funding to establish a digital lab, called ICT and Resource Center on Disability (IRCD), to develop assistive technologies and content for persons with disabilities.
In 2005, I was introduced to the Digital Accessible Information System (DAISY) Consortium, where I received inspiration from international experts to work harder and smarter, and make better use Continue reading

On 20 September 2017, Hurricane Maria made landfall in Puerto Rico. Two and a half months later, the island is still recovering from the resulting devastation. This extended phase of recovery is reflected in the state of the local internet and reveals how far Puerto Rico still has to go to make itself whole again.
While most of the BGP routes for Puerto Rico have returned, DNS query volumes from the island are still only a fraction of what they were on September 19th — the day before the storm hit. DNS activity is a better indicator of actual internet use (or lack thereof) than the simple announcements of BGP routes.
We have been analyzing the impacts of natural disasters such as hurricanes and earthquakes going back to Hurricane Katrina in 2005. Compared to the earthquake near Japan in 2011, Hurricane Sandy in 2012, or the earthquake in Nepal in 2015, Puerto Rico’s disaster stands alone with respect to its prolonged and widespread impact on internet access. The following analysis tells that story.
