The following is an analysis of the Amazon Web Services outage that occurred on December 15, 2021. While it may be the holiday season for many, it seems to be a Bill Murray-style Groundhog Day for AWS. For two consecutive weeks, outages occurred in the US-West-2 region in Oregon and the US-West-1 region in Northern California. This AWS outage lasted about an hour, affecting major services such as Auth0, Duo, Okta, DoorDash, PlayStation Network, Slack, Netflix, Snapchat, and Zoom. Catchpoint confirmed that the outage began around 7:15 AM Pacific Time, significantly earlier than AWS's announcement.

Defining the term "monitoring" is a challenging task, considering that the performance space has been evolving significantly year by year. Recently, there have been changes in the world of monitoring, leading to healthy discussions about the definitions and purposes of monitoring, during which a new term called "observability" has emerged. Many companies, such as AirBnB, Twitter, and Stripe, have created roles like observability teams and observability engineers to incorporate observability into their practices. So, what is the difference between monitoring and observability? And what kind of relationship do they have? *For more details about the blog, you can view it through the related links.

Internet outages can catch you off guard when you try to implement what is outlined in the incident response manual, whether you are an end user or the head of an SRE (Site Reliability Engineering) or DevOps department, while trying to maintain your composure. For those responsible for providing reliable services to customers, the usual outages include situations that should be resolved as quickly as possible, akin to a fire alarm or video call ringing. That said, we often forget what outages mean for end users. On Tuesday, November 16, 2021, for some reason, I was reminded of the feeling of having just put on mismatched shoes.

On August 31 (Tuesday), users in a wide area of the West Coast (US-West-2 region) were affected by a significant spike in response times. Among AWS's critical services, Lambda and Kinesis were impacted. The SRE team is concerned about service level indicators (SLIs) and service level objectives (SLOs), and this practice is essential for the SRE team. However, unlike Google, the founder of SRE, most companies rely on infrastructure and services from other providers like AWS and GCP, as well as multiple CDNs. This means that not only do their own applications and services need SLIs and SLOs, but they also need to carefully evaluate their providers and vendors. *For more details, you can refer to the related links.

Email is often the first choice for cybercriminals to initiate attacks because it is very easy to exploit. Unlike brute force attacks that require a large amount of processing power or sophisticated techniques that demand advanced skills, domain spoofing can be done as easily as writing an email pretending to be someone else. In many cases, that "someone else" is a major software service platform that people rely on for their work. This occurred when PowerDMARC's security analysts discovered a new wave of phishing emails targeting a major insurance company in the Middle East between April 15 and 30, 2020. This attack is just one of the recent increases in phishing and spoofing incidents during the Covid-19 crisis. Prior to this, in February 2020, another large-scale phishing scam occurred, where thousands of emails were sent impersonating the World Health Organization, soliciting donations for coronavirus relief. *For more details, you can view the blog through the related link.

Unlike DMARC, SPF behaves differently for each subdomain. If you are unsure whether to set up SPF for your subdomains or to implement a separate (DMARC) policy for them, this article may be helpful. To summarize briefly, the DMARC policy of a domain is automatically applied to its subdomains. This means that if there is a DMARC record with p=reject published for company.com, emails sent from subdomains like support.company.com or marketing.company.com will inherit the same DMARC policy as the zone apex domain, so there is no need to manually configure individual sp (subdomain policy) DMARC tags.

Websites are no longer just simple HTML pages with static content. They have transformed into dynamic interfaces equipped with various features, and the content is updated at regular intervals. Website administrators use various techniques to ensure that users can view new versions of pages and content. When new features are added to the site or when the resources of a web page are moved to a new location, users may not want them to access those pages. To prevent access, web page redirects are used. This allows the submitted HTTP requests to be redirected to other locations within the site, ensuring a seamless user experience. 【Overview】 ■ Role of Redirects ■ Types of Redirects ■ Performance Impact of Redirects ■ Common Redirect Errors ■ Proper Implementation of Redirects *For more details about the blog, you can view it through the related links.

In the past, there were many OA companies in Japan that specialized in the proliferation of PCs, handling corporate PC and software purchases, installation, and support (for inquiries about malfunctions and usage). However, nowadays, companies that outsource such services individually have almost disappeared. In small and medium-sized enterprises, it is common for knowledgeable employees in the general affairs department to handle these issues, or for system-related employees to manage them as a side task. In Japan, many are still struggling to respond effectively, often outsourcing to specialized companies (including web production companies), general advertising agencies, or internet-focused advertising agencies. In the United States, many of these tasks have become less about trial and error, allowing companies to focus more on activities that yield better results.
