Building the metaverse is one thing. Scaling it is another.

Did the volume of trick-or-treaters seem heavier than usual this year? It might not be your imagination. The Great Halloween Roblox Outage of 2021 forced tens of millions of children into a rare extended vacation from the metaverse. While the outage was no less than a living nightmare for Roblox players, it also provides a useful case study on the potential pitfalls of scaling an immensely popular platform.

The Roblox outage was unusual in both its duration and the size of the affected user base. Reports of widespread outages arrived on Thursday afternoon, and it wasn't until Sunday afternoon that all systems went back online.

• The outage likely sidelined upwards of 50 million users each day; Roblox reported 46.6 million daily active users in July 2021, which was up 8% from the previous month.
• On a typical day that month, each active user logged nearly 2 hours and 40 minutes of playtime on the platform.

The exact cause of the outage is still unknown. Roblox hasn't yet provided a detailed report on what caused the servers to go offline, but the company plans to release one soon. In the meantime, CEO David Baszucki wrote a blog post attributing the outage to a core infrastructure system becoming overwhelmed, which was "prompted by a subtle bug in our backend service communications while under heavy load."

• Roblox added that this failure "was caused by the growth in the number of servers in our datacenters."
• The fix took so long in part because Roblox experienced difficulty diagnosing the bug. Once engineers were able to figure it out, they "resolve[d] the issue through performance tuning, re-configuration, and scaling back of some load."

Roblox has grown its platform at warp-speed over the past year to accommodate the surge in concurrent users on its platform.

• The Roblox network operates in more than 180 countries. In 2020, Roblox first added multi-region core data center infrastructure applications in an effort to get rid of single points of failure in its systems.
• And to accommodate the additional capacity requirements, Roblox also transitioned away from utilizing global pools of compute resources to instead use regional pools serving customers in either the Americas, Asia or Europe.
• While embarking on these ambitious projects, Roblox nearly doubled its entire workforce in the course of a year. The company added 400 employees in 2020 to the 579 that started the year. Most of these individuals were hired for either product or engineering roles.

Roblox was trying to build the plane while flying it, to use a somewhat tired business metaphor. It's hard to place any blame on Roblox for attempting to capitalize on its tremendous popularity. The company didn't lack any obvious systems that could have prevented an outage.

• As recently as April 2021, for instance, Roblox detailed its efforts to build comprehensive network monitoring and fault detection systems.
• Rather than assigning blame to Roblox, it's more useful to highlight the inherent complexity that arises from scaling a network. Prioritizing capacity growth often comes at the expense of understanding how exactly that system works. And as the workforce grows, there's a smaller proportion of employees acquainted with the ins and outs of the platform. These dynamics help explain why it may have taken so long for Roblox to diagnose the problem.

It's also worth putting the outage into perspective. Many news outlets have pointed out that Roblox's market cap took a hit of around $1.5 billion following the outage. But Roblox says the outage did not result in a loss of player data, and the user experience has returned to normal. It also committed to making its creator community "economically whole," which is an important measure given Roblox's vision for its creator ecosystem. And if Roblox achieves its immensely ambitious goal of accruing 1 billion users, this outage will have come at a time with relatively low stakes and high learning upside.

Frances Haugen thinks Mark Zuckerberg should resign:

• "I think Facebook would be stronger with someone who is willing to focus on safety."

Jeff Bezos says it'll take a lot more than his $10 billion pledge to fight global warming:

• "It'll take trillions of dollars to make a dent in climate change … and it's going to take nation states, it's gonna take companies, and it'll take NGOs and nonprofits as well."

The metaverse is synchronous, which Facebook's Andrew Bosworth said will help users feel safer:

• "There are some advantages that the synchronous environment is going to have in terms of an individual being able to feel in control of themselves and their experience."

But Meta may not attract all the metaverse users it really wants, said Dave Carr, communications head at the virtual world Decentraland:

• "People who want to determine the future of the virtual worlds they inhabit, maintain ownership of their creative output and move freely between them will choose the decentralized version."

• "I'd like to emphasize that no contract has been signed yet. Tesla has far more demand than production, therefore we will only sell cars to Hertz for the same margin as to consumers."
