Today there is an ongoing, large scale Denial-of-Service attack directed against Dyn DNS. While Cloudflare services are operating normally, if you are using both Cloudflare and Dyn services, your website may be affected.
Specifically, if you are using CNAME records which point to a zone hosted on Dyn, our DNS queries directed to Dyn might fail making your website unavailable, and presenting a “1001” error message.
Some popular services that might rely on Dyn for part of their operations include GitHub Pages, Heroku, Shopify and AWS.
As a possible workaround, you might be able to update your Cloudflare DNS records from CNAMEs (referring to Dyn hosted records) to A/AAAA records specifying the origin IP of your website. This will allow Cloudflare to reach your origin without the need for an external DNS lookup.
Note that if you use different origin IP addresses, for example based on the geographical location, you may lose some of that functionality by using plain A/AAAA records. We recommend that you provide addresses for many of your different locations, so that load will be shared amongst them.
Customers with a CNAME setup (which means Cloudflare is not configured in your domain NS records) where the main Continue reading
But the Cisco partnership is still thriving.
A DNS service gets downed twice (so far) on Friday.
CoreOS announced that Redspread has joined the company to extend Kubernetes.
As DDoS attacks escalate, routers can't always keep up.
Widespread attack illuminates vulnerability of the Internet's Domain Name System (DNS) infrastructure.
Juniper Contrail is Software Defined Networking (SDN) controller which automate the network provisioning in a Virtual Data Center. In traditionally server hyper-visor environment there is still need to configure and allow VLANs on Data Center switches ports connected with servers, which involves inordinate delays due to lengthy “Change Process” approval and dependency on many teams. But modern centers can not afford such delays for service provisioning as delay in service provisioning means lost of revenue.
The scope of this blog is to discuss:-
Above diagram shows architecture of Contrail , quick overview of Contrail inner working described below, please follow the link for Contrail in depth reading (http://www.opencontrail.org/opencontrail-architecture-documentation/)
Over the last couple of years, we have been watching how burst buffers might be deployed at some of the world’s largest supercomputer sites. For some background on how these SSD devices boost throughput on large machines and aid in both checkpoint and application acceleration, you can read here, but the real question is how these might penetrate the market outside of the leading supercomputing sites.
There is clear need for burst buffer technology in other areas where users are matching a parallel file system with SSDs. While that is still an improvement over the disk days, a lot …

Since we launched Docker Labs back in May, we’ve had a lot of interest. So we keep adding more and improving the labs that we have. We now have 22 hands on labs for you to choose from, ranging from beginner tutorials to much more advanced ones. Here’s a peek at what we have:
So check out Docker Labs to learn more about using Docker. And as always, we really encourage contributions. So if you have a lab you want to get out there, or find a way to improve what we have, please contribute today.
