Understanding how Facebook disappeared from the Internet

Today at 1651 UTC, we opened an internal incident entitled "Facebook DNS lookup returning SERVFAIL" because we were worried that something was wrong with our DNS resolver 1.1.1.1. But as we were about to post on our public status page we realized something…

Amazon Managed Service for Prometheus

Prometheus is released under Apache-2. There are a lot of people and
companies that deploy Prometheus and even offer it as a service to their
customers, without collaboration whatsoever. And it is perfectly allowed
by the license. Every contribution upstream is therefore a success and a
bonus for our community and our users.

Prometheus strives to be an open project. Not only open as in open source,
but also open as in open and public discussions/roadmap. Everything I
note here is public, links are below.

Regarding AWS specifically:

Amazon Managed Service for Prometheus is actually not Prometheus, but
cortex (1). They are Cortex maintainers (2) (Note that a major
difference between Cortex and Prometheus is that in Cortex, the
companies somehow take a role in decision making (3). In prometheus
governance, we are all individuals).
AWS & Grafana labs have designed and coded the SNS intregration for
Alertmanager (4).
AWS is also committed to provide native ECS discovery (5) and have
upstreamed an ECS exporter (6).
This is only the tip of the iceberg. AWS is also engaged with supporting
Prometheus in the OpenTelemetry ecosystem (7).

Barrier

Barrier - это программное обеспечение, которое имитирует функциональность переключателя KVM .

KVM — Вещь полезная тем, у кого большой зоопарк железа, которое постоянно работает и он не хочет под каждый компьютер использовать отдельную клавиатуру/мышь и кто устал от бесконечных перетыркиваний проводов.

KVM гаджет позволяет подключить например: 4 компьютера к одной клавиатуре и одной мыши — и просто нажимая кнопки переключаться между устройствами.

Barrier делает тоже самое что и KVM , но без железа, то есть программно, позволяя указать какой машиной управлять, перемещая указатель мыши к краю экрана или используя нажатие клавиши для переключения фокуса на другую систему.

Barrier протестирован и работает на Windows, OSX, GNU/Linux, OpenBSD и FreeBSD
