Global Collateral Damage of TMnet leak

12322b_All_Sources-4

The Washington Post recently published a great piece about the development and current weaknesses of the Border Gateway Protocol (BGP, which is used to route all Internet traffic). This morning Telekom Malaysia (a.k.a TMnet) helped to illustrate the points made in the article by leaking almost half of the global routing table via Level 3 at 08:44 UTC.

Some of the most affected companies were those peering with Telekom Malaysia.  The following graphics illustrate the impact to routes from Amazon and Cloudflare.

Google’s extensive peering likely insulated it from some of the effects of having its routes leaked.  However, it didn’t escape the incident completely unscathed.  Here is an example of a normal traceroute to Google’s data center in Council Bluffs, Iowa from Prague, which goes via Frankfurt and London before crossing the Atlantic Ocean.

Four things to watch for as net neutrality rules go into effect

The U.S. Federal Communications Commission’s net neutrality rules went into effect Friday, after an appeals court denied multiple requests to delay them while the agency faces 10 lawsuits challenging the regulations.The rules prohibit broadband providers from selectively blocking or slowing Internet traffic and from charging website owners and providers of Web-based services for prioritized traffic. The rules also reclassify broadband from a lightly regulated information service to a more heavily regulated telecom-style service, although the FCC voted to exempt broadband providers from many of those common-carrier rules.Here are four things to watch for as the rules go into effect and the lawsuits go forward:To read this article in full or to leave a comment, please click here

PlexxiPulse—Partnering with CloudGov Technologies

This week we announced our partnership with CloudGov Technologies, a third platform IT Solutions provider servicing the government and commercial markets. This partnership helps federal agencies address the increasing need for scalable, agile and distributed data center networks built for third platform computing workloads. As a result of this partnership, a large U.S. government agency recently deployed our solutions to automate the provisioning and deployment of more than 30,000 virtual desktops with minimal administration. The deployment significantly improves application user experience and performance by optimizing the flow of east-west traffic across its virtualized data center.

Interested in learning more? Drop us a line at [email protected] to schedule a demo or stop by booth #7071 at the AFCEA Defensive Cyber Operations Symposium from June 16-18 in Baltimore. We will be showcasing our third platform solution alongside CloudGov Technologies.

Amazon boosts cloud offerings with souped-up virtual servers

Amazon Web Services has launched new, more powerful general-purpose and data-warehouse virtual servers as it works to stay ahead of the competition by offering users a wider array of cloud-service options.Amazon has had a busy week, expanding its portfolio on Tuesday and Thursday with new virtual servers, or "instances," for its public cloud.The M4 family is Amazon's latest generation of EC2 (Elastic Compute Cloud) general purpose instances. There are five sizes to choose among, each with up to 40 virtual CPUs and 172GB of system memory, Amazon said on Thursday.MORE ON NETWORK WORLD: How to build a private cloud The top size costs users from US$2.52 per hour when they pay on an on-demand basis.

IDG Contributor Network: 5 ways to fight mainframe malaise

As a mainframer, I belong to a number of organizations and groups that focus on this technology. And when I read message boards, Web sites, magazines, and blogs about big iron one theme always comes through loud and clear: my peers are overwhelmingly negative about their jobs.

In fact, some recent polls highlighting employee job dissatisfaction paint a fairly grim picture. A recent Gallup Poll is here. The Washington Post poll is here. And a Forbes poll is here.

A good start, but developers want more access to the Apple Watch

A software update to the Apple Watch’s OS gave third-party developers access to the device’s sensors this week, fulfilling a request they’ve had since Apple unveiled the wearable.With watchOS 2, which Apple showed on Monday at its annual developer’s conference, developers can create more-capable apps that directly tap into the watch’s components, like its microphone and heart rate sensor, instead of relying on an accompanying iPhone to handle app processing.While developers welcomed this news, some think Apple could go even further in making the watch a better platform for their apps.To read this article in full or to leave a comment, please click here

Report: Blackberry’s next devices could run Android

Beleaguered smartphone manufacturer Blackberry could go Android with its next device, abandoning development of its own platform in the interest of getting a more robust ecosystem of apps into the hands of its few remaining users, according to a report from Reuters.Citing anonymous sources, the news agency said that the idea is to transform Blackberry into a software and services company, centered on BES 12, a mobility management system designed to work across Android, iOS, and Windows Phone devices, in addition to Blackberry’s own.

According to the Data Center Journal:

What’s the problem with IT resumes? They’re useless.

The real problem with IT resumes, though, is we want to see a long list of technologies, because we want to find the specific technology we want to implement (or are implementing) — rather than a good engineer. The hiring process is a fishing expedition rather than a search for solid talent and personality fit. If we want to fix this problem we can. The question is — do we want to?

Bruce Schneier has some wise thoughts on airport security this week —

We don’t need perfect airport security. We just need security that’s good enough to dissuade someone from building a plot around evading it. If you’re caught with a gun or a bomb, the TSA will detain you and call the FBI. Under those circumstances, even a medium chance of getting caught is enough to dissuade a sane terrorist

Replace “airport” with “network,” and you get the drift of where network security is going, I think. Of course, there’s the reality that you can’t stop insane attackers… Worth remembering. The same point can be made for network uptime, by the way. Perfection is Continue reading

Massive route leak causes Internet slowdown

Earlier today a massive route leak initiated by Telekom Malaysia (AS4788) caused significant network problems for the global routing system. Primarily affected was Level3 (AS3549 – formerly known as Global Crossing) and their customers. Below are some of the details as we know them now.

Starting at 08:43 UTC today June 12th,  AS4788 Telekom Malaysia started to announce about 179,000 of prefixes to Level3 (AS3549, the Global crossing AS), whom in turn accepted these and propagated them to their peers and customers. Since Telekom Malaysia had inserted itself between these thousands of prefixes and Level3 it was now responsible for delivering these packets to the intended destinations.

This event resulted in significant packet loss and Internet slow down in all parts of the world. The Level3 network in particular suffered from severe service degradation between the Asia pacific region and the rest of their network. The graph below for example shows the packet loss as measured by OpenDNS between London over Level3 and Hong Kong. The same loss patterns were visible from other Level3 locations globally to for example Singapore, Hong Kong and Sydney.

LTE subscriptions to surpass 1 billion this year

The number of LTE subscriptions will pass 1 billion before the end of the year, prompting operators to invest in technologies such as small cells to keep up.There will be nearly 1.37 billion 4G LTE subscribers around the world by year-end, up from nearly 650 million in 2014, according to market research company ABI Research. LTE’s growing popularity is helped by a number of things: mobile operators including the technology in more of their plans, cheaper LTE smartphones and aggressive network expansions in countries like China.LTE is being rapidly embraced in North America, Japan and South Korea where it’ll be included in a majority of subscriptions this year, according to telecommunications equipment maker Ericsson, which last week published a report on its expectations for future mobile growth.To read this article in full or to leave a comment, please click here
