Understanding How Facebook Disappeared from the Internet<\/a><\/div>\n
\n

Facebook\u2019s outage caused significantly increased load on DNS resolvers, among other effects. Cloudflare also published this followup article<\/a> with more findings.<\/p>\n

The New Norm<\/a><\/div>\n
\n

Shell (the oil company) reduced accidents by 84% by teaching roughnecks to cry. Listen to this podcast (or check it out in article form<\/a> to find out how. Can we apply this to SRE?<\/p>\n

Don\u2019t have time to read Google\u2019s entire report? Here are the highlights.<\/p>\n

More details about the October 4 outage<\/a><\/div>\n
\n

I really like how open Facebook engineering has been about what went wrong on Monday. This article is an update on their initial post<\/a>.<\/p>\n

Tools to explore BGP<\/a><\/div>\n
\n

Want to learn about BGP? Ride along as Julia Evans learns. I especially like how she whipped out strace to figure out how traceroute was determining ASNs.<\/p>\n

Announcing the VOID<\/a><\/div>\n
\n

The Verica Open Incident Database is an exciting new project that seeks to create a catalog of public incident postings. Click through to check out the VOID and read the inaugural paper with initial findings. I\u2019m really excited to see what this project brings!<\/p>\n

\u2018date -d\u2019 vs. \u2018date -s\u2019, and \u2018show foo\u2019 vs. \u2018clear foo\u2019<\/a><\/div>\n
\n

Printing versus setting a date \u2014 they\u2019re only separated by a typo. Perhaps something similar happened with Facebook\u2019s outage.<\/p>\n

SRE Doesn\u2019t Scale<\/a><\/div>\n
\n

Adopting a microservice architecture can strain your SRE. This article highlights an oft-missed section of the SRE book about scaling SRE.<\/p>\n

Outages<\/h2>\n

Facebook, Instagram, WhatsApp, and Oculus<\/a><\/p>\n

Well, that sure was a big one. Facebook and related services were totally down for 6+ hours \u2014 even their DNS servers.They also had another, smaller outage<\/a> later in the week.<\/p>\n

Slack<\/a><\/p>\n

Not a real outage, but Slack reported that users were having a hard time connecting to Slack, because resolvers were overloaded by DNS lookups for facebook.com.<\/p>\n
