For more than two hours on Thursday, June 6, a large chunk of European mobile traffic was rerouted through the infrastructure of China Telecom, China's third-largest telco and internet service provider (ISP).
The incident occurred because of a BGP route leak at Swiss data center colocation company Safe Host, which accidentally leaked over 70,000 routes from its internal routing table to the Chinese ISP.
The Border Gateway Protocol (BGP), which is used to reroute traffic at the ISP level, has been known to be problematic to work with, and BGP leaks happen all the time.
However, there are safeguards and safety procedures that providers usually set up to prevent BGP route leaks from influencing each other's networks.
But instead of ignoring the BGP leak, China Telecom re-announced Safe Host's routes as its own, and by doing so, interposed itself as one of the shortest ways to reach Safe Host's network and other nearby European telcos and ISPs.
That bicycle helmets are not currently tested against such impacts will be a revelation to many cyclists and motorists, many of whom erroneously assume that bicycle helmets offer greater protection than they are actually designed to provide.The helmet is a lie. It always has been.
Results show the majority of news reports were episodic rather than thematic, focusing on the traffic event and the parties involved in the crash, particularly the bicyclist. Vocabulary, grammatical structure, and narrative framing of news reports largely functioned to remove blame from the motorist and to highlight the bicyclist’s actions. These linguistic strategies reflect the assumption that responsibility for safety rests on the bicyclist and detracts attention from potential social policy reform that would lead to fewer bicyclist fatalities.#bicycle #cycling #traffic #safety #science #car #collision #accident #news #media
The latest study, however, shows that’s not the case. Figures show these dial-a-ride taxi fleets have increased congestion [in San Francisco] by 62 per cent in 2016 compared to 2010. Drivers often cruise around in between trips waiting for nearby passengers to order rides via apps on their phone, a process known as deadheading. It is estimated that 20 per cent of the miles traveled by Uber and Lyft cars are from deadheading.Who could possibly have predicted this would happen, with the crippling shortage of parking in San Francisco?
Splitting the cost of journeys on these services makes rides cheaper, and it means that people have chosen to take Uber or Lyfts over other modes of transport. The researchers reckon that some 43 per cent to 61 per cent of all ride-sharing trips could have been swapped for walking, public transport, or cycling.https://www.theregister.co.uk/2019/05/09/uber_and_lyft_rides/
