Comcast endures major Internet outage on the East Coast

By Aemon Malone November 29, 2010

Comcast’s Internet service suffered an outage on Sunday that left East Coast subscribers without online access for several hours. Complaints began to surface on Twitter late yesterday evening and appeared to be relegated to subscribers in Boston, Washington, DC, and the surrounding areas.

Shortly after reports of the outage began surfacing, some Twitter users began posting workarounds involving switching Domain Name System (DNS) settings. DNS works by translating the numerical Internet Protocol addresses into the domain names that humans can read (like www.digitaltrends.com). By flipping DNS settings from those Comcast provided to either OpenDNS or Google’s Public DNS users were able to restore connectivity.

Comcast announced that it had fixed the problem shortly after midnight and just in time for the official start of Cyber Monday, the Internet’s version of Black Friday. It’s not clear how many customers were affected by the outage or what the exact cause was, but neither cable television nor phone service appear to have been impacted.

AMD Ryzen AI claimed to offer ‘up to 75% faster gaming’ than Intel

AMD has just unveiled some internal benchmarks of its Ryzen AI 9 HX 370 processor. Although it's been a few months since the release of the Ryzen AI 300 series, AMD now compares its CPU to Intel's Lunar Lake, and the benchmarks are highly favorable for AMD's best processor for thin-and-light laptops. Let's check them out.

For starters, AMD compared the Ryzen AI 9 HX 370 to the Intel Core Ultra 7 258V. The AMD CPU comes with 12 cores (four Zen 5 and eight Zen 5c cores) and 24 threads, as well as 36MB of combined cache. The maximum clock speed tops out at 5.1GHz, and the CPU offers a configurable thermal design power (TDP) ranging from 15 watts to 54W. Meanwhile, the Intel chip sports eight cores (four performance cores and four efficiency cores), eight threads, a max frequency of 4.8GHz, 12MB of cache, and a TDP ranging from 17W to 37W. Both come with a neural processing unit (NPU), and AMD scores a win here too, as its NPU provides 50 trillion operations per second (TOPS), while Intel's sits at 47 TOPS. It's a small difference, though.
