The Good, The Bad, and the League: 1/4 - 1/21
_Your semi-weekly dose of server problem-os, NA League news, and other! _
2020 has started! We’ve got LCS about to start, LoR is soon to enter open beta, Sett is punching an awful lot of things, and everyone loves giant Mechs.
Follow-Ups:
- Mac voice still not working properly Bug grouped with other Mac bugs. More .plist fun (No progress since last check).
Ongoing
- Server Transfers Disabled Transfers are disabled until the next platform downtime (likely 10.3), in order to install additional logging and diagnostic tools to improve transfers in the long run.
**Server Stuff: **
-
Aphelios’ Passive/R/E abilities in LCU video not loading(12/10, ~1 month) NOC is notified that Aphelios’ Passive/W/E videos in LCU don’t work. Needless to say, they failed to work because the videos were designed in LCU format to work with a champion with 1 passive and 4 abilities. Since the problem couldn’t be micropatched out, it needed to be fixed with 10.1.
-
PayOn payments not resolving properly(1/9, ~184 minutes) Reports filter in that there’s problems with PayOn. Engineers discover the issue isn’t on League’s side, and work with PayOn engineers to fix the problem.
-
Sign on problem increases(1/13, ~29 minutes) Automated alerting notifies the NOC that signing in problems are reaching problematic levels. Investigation leads to a dependent service (the backup) wasn’t properly resolving issues when the primary was having problems. Updates will need to be made to the dependent service to prevent this from happening in the future.

Players unable to log into Riot services(1/14, ~61 minutes) Automated alerting notifies the NOC that sign on errors are reaching unacceptable levels. Engineers find that a core part of the sign in process isn’t responding to requests. Issues expand to impact other core services as well. Engineers need to spin up new instances and help offset the load as the systems start to recover.
-
High CPU Utilization across game servers, requiring mitigation steps(1/15, ~178 minutes) Due to warning levels of CPU utilization, NOC technicians set minimum numbers for custom games, as well as enabling queues for TFT and ARAM. As usage lowers, throttles are removed.

Social Panel missing from LoL Client(1/16, ~6 hours) A change is made to the backend servers during a change window. However, the change sees the social panel go down. Issue starts to impact all regions, and a triage team starts work on a hotfix. The hotfix is about to be deployed, only to find it’d cause another problem if deployed as is. Hotfix undergoes another QA pass and is approved for deployment, which solves the problem.
**Game Stuff: **
- ARAM expanded F2P rotation list not updating(12/23, ~1 month) NOC is notified that changes fail to execute on the F2P rotation list. Investigation leads to the expanded F2P rotation as a starting point. Investigation ends noticing that it happened due to a manual config change that was incorrect.
