Ensure Quality of Experience and Readiness with CDN Capacity Overflow Have you ever planned and launched a system with painstaking detail and, at some point in time, something unexpected breaks the system? An unexpected event might be an unanticipated scenario (a bug!) or user adoption beyond expectations (hello Fortnite!). These events can lead to gut-wrenching times when a fix to address the event takes a long time even though the
Twenty years ago it would be common to have multiple data centers load balanced with specialized devices. The applications in multiple data centers would use the Domain Name System (DNS) to look up the application destination. The DNS system would be set up to with multiple data center locations. This would "round robin" the results between the data centers. If you have four data centers, the customers would get "round-robined"
Everyone and everything on the Internet depends on the Domain Name System (DNS) being functional. The DNS has been a common vector for attacks in recent years, and 2019 seems to be no different. Many of these attacks have goals far more sinister than simply taking a company offline or defacing a website; reported attacks include redirecting some or all of an organization's domain to gain access to protected
Written by Jon Reed & Barry Greene DNS Flag Day is an industry event that promotes the adoption of the most up-to-date DNS features and ensures that non-standards-compliant servers don't negatively impact the global performance of the Internet. The 2019 DNS Flag Day will remove a number of workarounds regarding servers that do not fully support the EDNS0 (RFC 6891) extensions.
Domain Name Consolidation The market and marketing of Web property domain names is changing. Companies prefer to promote top level domains (TLDs), have the option of selecting brand-relevant domain extensions (e.g. SaaS.com), and no longer need country-relevant domains to optimize search engine result rankings. This provides an opportunity to reduce "domain name fragementation" but also presents business and technical challenges if a migration is required from the active use of
Yes, we can minimize the BGP Hijacking Risk Every day we see something new about the global security threat. It is hard to keep track of all the various ways your network can be attacked. But there are some threat-vectors which need particular attention. "Did you know that a threat-actor with 20 BGP speaking routers can cause massive disruption in telecommunications all over the world?" "Did you know that someone
The Domain Name System (DNS) is one of the Internet's fundamental systems, providing the top-level hierarchy for naming Internet resources. One of its purposes is to act as a sort of phonebook, allowing names such as "www.example.com" to be resolved to resource information, such as server IP addresses. It provides the hierarchical naming model that enables clients to "resolve" or "lookup" resource records associated with names. This naming hierarchy also
Like many other security professionals, you have been reviewing your security stack, reading up on the latest security trends, and have perhaps recently attended Info-Sec, RSA, Black Hat or some other relevant conference. Along the way, you may have seen messaging for recursive DNS (rDNS) as a security layer. However, it's hard for you to believe DNS is an effective security control, as you know it is a lookup service
Every year, tens of thousands of mergers and acquisitions (M&A) take place across every industry and vertical. In fact, "In 2017, companies announced over 50,600 transactions with a total value of more than 3.5 trillion USD." Not only is M&A complex from a business sense, it also brings the challenge of merging complex IT infrastructures and applications (which are only getting more complex) as businesses move away from a perimeter
