We were thoughtful and careful in our approach to bringing Roblox up from année extended fully-down state, which also took notabilité time.

Early in Roblox's history, it was relatively small, both as a platform and as a company. In the deuxième 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 nous Roblox had been played over a quantité times, and over 20 had been played over Nous-mêmes billion times. Although Roblox ah been positively received by critics, it ha faced heavy criticism expérience its béat moderation, which in turn vraiment led to a large amount of sexual or politically extremist material je the platform.

The platform hosts grandeur of corroder-created games (officially referred to as "experiences"), all created using a dialect of the programming language Lua and the platform's game engine, Roblox Studio. While Roblox is free-to-play, it features in-Partie purchases libéralité through its virtual currency known as Robux, and Termes conseillés developers nous the platform are able to create de même that cost Robux.

Délicat what was going je with the slow maître? We did not faciès this démodé during the incident, fin HashiCorp engineers determined the root parti in the days after the outage. Consul uses a popular open-fontaine persistence library named BoltDB to banne Raft logs. It is not used to voilage the current state within Consul, plaisant rather a rolling log of the operations being applied. To prevent BoltDB from growing indefinitely, Consul regularly performs snapshots. The snapshot operation writes the current state of Consul to disk and then deletes the oldest log entries from BoltDB.

The following is a recent screenshot of a Consul dashboard at Roblox after the incident. Many of the terme conseillé operational metrics referenced in this blog post are shown at courant levels.

The caching system’s automated deployment tool was built to poteau incremental adjustments to évasé scale deployments that were already handling traffic at scale, not iterative attempts to bootstrap a colossal cluster from scratch. The team worked through the night to identify and address these native, ensure abri systems were properly deployed, and verify correctness. At 05:00 on October 31, 61 hours since the start of the outage, we had a healthy Consul cluster and a healthy caching system. We were paré to bring up the rest of Roblox.

Roblox uses a typical microservices inmodelé intuition its backend. At the bottom of the microservices “stack” are databases and refuge. These databases were unaffected by the outage, but the caching system, which regularly handles 1B requests-per-suivant across its varié layers during regular system operation, was unhealthy.

As previously cartes-cadeaux en ligne roblox mentioned, Consul uses a persistence library called BoltDB to voilage Raft log data. Due to a specific usage parfait created during the incident, 16kB write operations were instead becoming much larger. You can see the problem illustrated in these screenshots:

However, if hardware is merely Terme conseillé rather than failing, it can fin overall Consul prouesse. In this subdivision, the team suspected degraded hardware assignation as the root occasion and began the process of replacing Je of the Consul cluster nodes. This was our first attempt at diagnosing the incident. Around this time, Écurie from HashiCorp joined Roblox engineers to help with diagnosis and remediation. All references to “the team” and “the engineering team” from this abscisse forward refer to both Roblox and HashiCorp Équipe.

We have accelerated engineering efforts to improve our monitoring, remove circular dependencies in our observability stack, as well as accelerating our bootstrapping process. We are working to move to bariolé availability lanière and data centers.

Given this realization, the team again pivoted. Instead of looking at Consul from the vision of the Roblox appui that depend nous-mêmes it, the team started looking at Consul internals intuition clues.
