Build Changes (gps)

(Build changes of which engineers should be aware.)

RelEng (catlee)

(Repo, test, and other information for engineers from the release engineering team.)

• Have switched our Amazon instances to use SSD backed EBS volumes. The goal is further cost reduction in AWS since we used to pay quite a bit for I/O on the old EBS volumes, but I/O on the new SSD volumes is free. We may see some slight performance wins as well.
  • https://aws.amazon.com/blogs/aws/new-ssd-backed-elastic-block-storage/
  • bug 1028341, bug 1027390
  • Please let us know if you see some bustage that could be due to this!

Upcoming Outages/Upgrades

(System outages/upgrades and tree closures that impact engineering.)

Quality Programs

OrangeFactor (ryanvm)

<Read Only>

• Past week's OrangeFactor: 9.67 (Previous Week: 7.36).

Stability (kairo/bsmedberg)

• current numbers still do not look good, except Android release.
• Still looking for older Intel integrated graphics machine to reproduce bug 988549 which continues to be high on 31 beta.
