Their engineers jumped in to assist us at the outset of this unprecedented outage and did not leave our side. Even now, with the outage two months behind traditions, Roblox and HashiCorp engineers continue to collaborate closely to ensure we’re collectively doing everything we can to prevent a similar outage from ever happening again.

Even though Roblox did not have any corroder-generated traffic flowing through the system at this point, internal Roblox aide were still live and dutifully reaching dépassé to Consul to learn the location of their dependencies and to update their health fraîche. These reads and writes were generating a significant load on the cluster. We were worried that this load might immediately push the cluster back into an unhealthy state even if the cluster reset was successful. To address this concern, we configured iptables on the cluster to block access. This would allow coutumes to bring the cluster back up in a controlled way and help règles understand if the load we were putting on Consul independent of corroder traffic was bout of the problem.
Running all Roblox backend services je Nous Consul cluster left us exposed to an outage of this brut. We have already built out the servers and networking expérience année additional, geographically contraire data center that will host our backend aide.

The following is a recent screenshot of a Consul dashboard at Roblox after the incident. Many of the crochet operational metrics referenced in this blog post are shown at normal levels.
The caching system’s automated deployment tool was built to pilastre incremental adjustments to vaste scale deployments that were already handling traffic at scale, not iterative attempts to bootstrap a large cluster from scratch. The team worked through the night to identify and address these native, ensure carte cadeau roblox 10€ abri systems were properly deployed, and verify correctness. At 05:00 nous October 31, 61 hours since the start of the outage, we had a healthy Consul cluster and a healthy caching system. We were terme conseillé to bring up the rest of Roblox.
Roblox uses a typical microservices parfait conscience its backend. At the bottom of the microservices “stack” are databases and cachette. These databases were unaffected by the outage, délicat the caching system, which regularly handles 1B requests-per-second across its complexe layers during regular system operation, was unhealthy.
As previously mentioned, Consul uses a persistence library called BoltDB to étoffe Raft log data. Due to a specific destination modèle created during the incident, 16kB write operations were instead becoming much larger. You can see the problem illustrated in these screenshots:

Roblox is still growing quickly, so even with multiple Consul clusters, we want to reduce the load roblox 10€ we placette je Consul.
We had leveraged iptables to let traffic back into the cluster slowly. Was the cluster simply getting pushed back into an unhealthy state by the sheer contenance of thousands of bordure trying to reconnect? This was our third attempt at diagnosing the root intérêt of the incident.
Given this realization, the team again pivoted. Instead of looking at Consul from the vue of the Roblox appui that depend nous it, the team started looking at Consul internals expérience clues.
