The team began to prep the hardware: Consul was installed, operating system forme triple checked, and the mécanisme readied expérience Bienfait in as detailed a manner as réalisable. The team then transitioned the Consul cluster back to 64 CPU Core servers, plaisant this échange did not help. This was our fourth attempt at diagnosing the root parti of the incident.
Early in Roblox's history, it was relatively small, both as a platform and as a company. In the suivant half of the 2010s, the platform began to grow rapidly, and this growth was accelerated by the COVID-19 pandemic. By 2020, over 5,000 games on Roblox had been played over a grandeur times, and over 20 had been played over Nous-mêmes billion times. Although Roblox vraiment been positively received by critics, it eh faced heavy criticism connaissance its satisfait moderation, which in turn has led to a étendu amount of sexual pépite politically extremist material nous the platform.
The first two attempts to terme conseillé the Consul cluster to a healthy state were unsuccessful. We could still see elevated KV write latency as well as a new inexplicable symptom that we could not explain: the Consul dirigeant was regularly dépassé of sync with the other voters. The team decided to shut down the entire Consul cluster and reset its state using a snapshot from a few hours before – the beginning of the outage. We understood that this would potentially incur a small amount of system config data loss (not fatiguer data loss). Given the severity of the outage and our confidence that we could restore this system config data by hand if needed, we felt this was acceptable. We expected that restoring from a snapshot taken when the system was healthy would bring the cluster into a healthy state, joli we had Nous additional concern.
Several months ago, we enabled a new Consul streaming feature je a subset of our faveur. This feature, designed to lower the CPU utilisation and network bandwidth of the Consul cluster, worked as expected, so over the next few months we incrementally enabled the feature nous more of our backend aide. Nous-mêmes October 27th at 14:00, Nous-mêmes day before the outage, we enabled this feature nous-mêmes a backend Aide that is responsible connaissance traffic routing. As part of this rollout, in order to prepare expérience the increased traffic we typically see at the end of the year, we also increased the number of nodes supporting traffic routing by 50%.

Roblox was officially released nous-mêmes September 1, 2006,[39] with Roblox Logement being made available that same year. Games that were made by the community early in the platform's history included paintball games, haunted houses, and model convoi that players could sillage. In 2008, the Roblox Confrérie stopped actively creating their own games to demonstrate the platform's capabilities, becoming entirely reliant on miner-created games.
Finally, we want to thank our Roblox colleagues for validating why this is année amazing agora to work. At Roblox we believe in civility and considération. It’s easy to Si civil and respectful when things are going well, but the real exercice is how we treat Nous-mêmes another when things get difficult. At some position during a 73-hour outage, with the clock ticking and the Invasion immeuble, it wouldn’t Lorsque surprising to see someone lose their calme, say something disrespectful, pépite wonder aloud whose fault this all was.
We would like to reiterate there was no râper data loss pépite access by unauthorized portion of any nouvelle during the incident.
The HashiCorp engineering team is creating new laboratory benchmarks to reproduce the specific contention native and performing additional scale épreuve. HashiCorp is also working to improve the Stylisme of the streaming system to avoid contention under extreme load and ensure sédentaire geste in such Formalité. Further analysis of the Indolent responsable problem also uncovered the passe-partout prétexte of the two-suivant Raft data writes and cluster consistency native. Engineers looked at flame graphs like the Nous below to get a better understanding of the inner workings of BoltDB.
While players were allowed to return to Roblox nous-mêmes October 31st, Roblox and HashiCorp continued refining their understanding of the outage throughout the following week. Specific contention originaire in the new streaming protocol were identified and isolated. While HashiCorp had benchmarked streaming at similar scale to Roblox maniement, they had not observed this specific behavior before due to it manifesting from a combination carte cadeau roblox 5€ of both a évasé number of streams and a high churn lérot.
Given the severity of the incident, the team decided to replace all the nodes in the Consul cluster with new, more powerful mécanique. These new mécanique had 128 cores (a 2x increase) and newer, faster NVME SSD disks.
It has been 2.5 months since the outage. What have we been up to? We used this time to learn as much as we could from the outage, to adjust engineering priorities based nous-mêmes what we learned, and to aggressively harden our systems. Nous of our Roblox values is Attention The Community, and comment recharger une carte roblox while we could have issued a post sooner to explain what happened, we felt we owed it to you, our community, to make significant progress on improving the reliability of our systems before publishing.
This drop coincided with a significant degradation in system health, which ultimately resulted in a complete system outage. Why? When a Roblox Prestation wants to talk to another Appui, it relies nous Consul to have up-to-Journée knowledge of the Loyer of the service it wants to talk to.
