The central characteristic of Twitter’s outage final Wednesday was a message to customers that “You are over the daily limit for sending Tweets.” A spokesperson for community enterprise agency Ookla, which owns outage monitoring website Downdetector, mentioned that on Feb. 8, beginning at 10 a.m. UTC, about 50,000 Twitter customers reported entry points.
While the Twitter outage affected comparatively few Twitter customers, it may maintain a bigger message in regards to the risks not simply to operations but additionally safety for organizations mulling large cuts in workforce.
With simply 1,300 energetic workers, Twitter now has 80% fewer staff than the roughly 8,000 the corporate had on its payroll earlier than the October 2022 takeover by Elon Musk, by some studies. Among his early choices on taking the helm have been to close down one in every of Twitter’s knowledge facilities and fireplace half the workforce.

Cut workers now, pay later
Reportedly, most of the Twitter staff who have been let go or who’ve walked out voluntarily in current months have been engaged on initiatives which can be elementary to firm operations, and former staffers and observers alike predicted that firing staff would result in simply the sorts of outages the corporate is experiencing.
Justin Cappos, professor of pc science on the NYU Tandon School of Engineering, developer of the in-toto provide chain safety framework and a member of the Linux Advisory Team, supplied a sports-friendly analogy:
“Imagine someone buys a professional sports team then looks around and says ‘You know, we need these coaches over here because they call the plays, but we don’t need the strength coach, the conditioning coach and we don’t need the nutritionist.’ So, when that team goes out and plays next week, they will play about as well as they did last week, and a week later maybe similar, but a month later they start to take a hit, and then the wheels start to fall off. That’s what’s happening; he has fired people who are doing the work that keeps this large distributed service running.”

Adam Marrè, chief info safety officer at cybersecurity operations agency Arctic Wolf, concurred that the outage means there are actually possible too many vacant IT chairs on the blue hen’s command heart.
“If an understaffed team is trying to change things quickly, that can be a recipe for unintended consequences with downstream or ancillary dependencies to code you are changing,” Marrè mentioned. “They won’t have the capability to handle entry provisions and offboard customers in a well timed style, and in circumstances like an outage, get techniques again up and working shortly.
“With an under-resourced team, the maintenance of tools across the enterprise stack may fall by the wayside, as priorities shift and adjust to reflect a team’s limited bandwidth.”
Twitter: Both outlier and emblem of job cuts in tech
Twitter’s workers cuts are distinctive due to the extraordinarily excessive proportion of the corporate’s whole worker inhabitants being offboarded, however the firm just isn’t alone. TrueUp’s Tech Layoff Tracker discovered that over 400 tech firms have laid off staff in 2023, with 127,359 folks affected. Complicating issues, over the previous a number of months, safety corporations have additionally slimmed their ranks, together with Okta, SecureWorks and Snyk, Sophos, Lacework, and OneTrust.

The U.S. Bureau of Labor Statistics predicted safety analyst jobs will develop by 35% between 2021 and 2031 with 19,500 openings for info safety analysts projected every year (Figure A).

Marrè mentioned layoffs might, to some extent, represent an adjustment after a hiring spree through the COVID-19 pandemic.
“Actually many companies, including tech companies, are still hiring,” Marrè mentioned. “Set in opposition to the backdrop of huge hiring that was carried out through the years of the pandemic, the final job cuts throughout the tech trade don’t appear as vital — in fact, job cuts are all the time vital for these straight affected.
“The good news is there are still many unfilled job openings out there for tech workers, so optimistically, this will end up being more of a reshuffling than a massive downsizing.”
With GitHub downsizing, safety automation taking over slack?
Among tech cuts lately introduced, each Microsoft’s GitHub unit and competitor GitLab introduced plans to downsize by 10% and seven% of workers, respectively. GitHub, which has a reported 3,000 staff, will go absolutely distant, per preliminary protection in Fortune — Microsoft’s CEO in January introduced plans to chop 10,000 jobs by fiscal 2023, or 5% of its workforce.
The 300 jobs GitHub plans to chop constitutes a comparatively small quantity within the scheme of issues, however the code hub is utilized by over 100 million builders and claims to have greater than 372 million open-source code repositories utilized by software program builders worldwide.
Although using open-source code has quite a few safety implications, Cappos mentioned the appearance of DevSecOps has improved the safety atmosphere and made it simpler for builders to work quick inside cloud environments like AWS with out sacrificing safety. This takes some strain off of workers who might, a minimum of within the brief time period, have fewer colleagues available.
“The DevSecOps paradigm started with lightweight containerization and microservice architecture because of Kubernetes,” Cappos mentioned. “The approach safety caught up is that individuals have carried out a variety of work to make issues like Kubernetes not as simple to misconfigure.
“There are a lot of really great software projects and security projects in that space, and Kubernetes has a very good security team working on this. They have made it more difficult to shoot oneself in the foot; they have defined better tooling around it so that people who do DevOps work can do security as part of that.”
Martin Mao, co-founder and CEO of cloud-native knowledge and metrics firm Chronosphere, identified that Prometheus is the de facto customary of Kubernetes monitoring immediately.
“We work with Julius Volz, one of that project’s creators,” Mao mentioned. “I do think investments in open source are here to stay, and I think every company will continue to recognize that they need to be aware of issues and continue to address them.”
Looking on the previous months’ tech layoffs, virtually no crew inside an organization is sacrosanct, and Mao argues that on the finish of the day, most firms wish to automate extra of their human-run processes for scale and effectivity.
“It’s important to remember, though, that moving to DevOps or DevSecOps or platform engineering means that you are purposefully transferring complexity from one solution to another,” Mao mentioned.
He mentioned that, in the perfect of all worlds, safety tech workers would acquire the identical advantages as different groups from working in a DevOps or DevSecOps paradigm: much less low-level work, much less combating fires and extra time to be proactive about their firm’s safety posture.
Former staffers as assault vectors
Is there an elevated safety threat consequent to staffing cuts, doubtlessly worsened by poor organizational hygiene? Marrè mentioned sure, pointing, for instance, to the potential for insider threats after the so-called Great Resignation and the necessity for correct protocols for deprovisioning customers.
“People who have been laid off may become the next target or vehicle to deploy ransomware attacks,” Marrè mentioned. “Bad actors will most probably proceed to supply ex-employees cash in trade for person credentials to achieve entry to essential techniques and infrastructures or provide them cash in trade for details about the corporate which can be utilized to assault it.
“Insider threat is always a risk, but large-scale layoffs and widespread employee dissatisfaction increases that risk significantly.”
Transparency is essential to incident response
Marrè means that firms with outages, whether or not of their cloud operations, on-premises techniques or buyer engagement platforms ought to:
- Communicate clearly and successfully with prospects about the issue, the standing and the in-progress answer.
- Make certain they’ve plans to take care of the elevated workload per worker to take care of the identical infrastructure and techniques as after they have been absolutely staffed.
He added that stopping disruptions requires retaining folks in key positions with institutional information of infrastructure and operations, together with safety operations.
“This can allow organizations to maintain uptime without significant outages and remain resilient in the face of incidents,” Marrè mentioned. “Cuts across those roles can have an asymmetrically impactful effect on quality of service as compared to other roles in the company.”
The dangers of doing extra with much less
Mao famous that, throughout the board, his agency is seeing that the engineering groups at many tech firms are actually being requested to do extra with much less and that firms want to concentrate.
“I think that the message here is companies need to understand how much work and complexity is being absorbed by employees running around with their hair on fire,” Mao mentioned. “Every outage has a root cause, but during an outage, it comes down to employees who have to find, understand and fix the problem.”
Chronosphere lately performed analysis displaying that builders and engineers spend a minimum of 1 / 4 of their work time performing low-level troubleshooting duties.
“If a company is asking fewer employees to monitor more systems, then there is a higher likelihood of an issue slipping past undetected and spiraling into a much bigger problem,” Mao mentioned. “And, unfortunately, many of the systems in place today are ill-equipped to lend a helping hand.”
