In May 2023, we announced our limited release of two new Heroku Private Spaces regions: India (Mumbai) and Canada (Montreal). This month, we’re announcing the full general availability of those two regions, along with new Heroku Private Spaces regions for the United Kingdom (London) and Singapore. This expansion enables customers to maintain greater control over where their data is stored and processed. These four new regions fully support Heroku Private Spaces, Heroku Shield Private Spaces, Heroku Postgres, Apache Kafka on Heroku, Heroku Data for Redis, Heroku Connect, and most Heroku Add-ons.
Private Spaces …

Subdomain reuse, also known as subdomain takeover, is a security vulnerability that occurs when an attacker claims and takes control of a target domain. Typically, this happens when an application is deprecated and an attacker directs residual traffic to a host that they control.
As of 14 June 2023, we changed the format of the built-in herokuapp.com domain for Heroku apps. This change improves the security of the platform by preventing subdomain reuse. The new format is <app-name>-<random-identifier>.herokuapp.com. Previously, the format was <app-name>.herokuapp.com. The new format for built-in herokuapp.com domains is on by default for all users.

Heroku is excited to announce the addition of a third availability zone (AZ) for our Private Spaces product offering. Three availability zones make Private Space apps more resilient to outages. We’ve prioritized this improvement as part of our focus on mission-critical features to make the Heroku Platform even more reliable. The changeover to three availability zones is fully managed by Heroku. Heroku handles all maintenance, upgrades, and management of Private Spaces, so our customers can focus on delivering value to their users without worrying about the underlying infrastructure.
What are availability zones and how does Heroku use them?

Webhooks are a more secure, reliable, and powerful alternative to Deploy Hooks, and five years ago, we made app webhooks Generally Available. Today, we are deprecating Deploy Hooks and encouraging customers to migrate to app webhooks.
Starting October 17, 2022, we will stop accepting new deploy hooks. Existing hooks will continue working until the product is sunset on February 17, 2023, but we encourage you to migrate your hooks as soon as possible.
There are many benefits to moving from Deploy Hooks to app webhooks, including:
App webhooks are more secure — You can verify that the messages you …

This following story outlines a recent issue we saw with migrating one of our internal systems over to a new EC2 substrate and in the process breaking one of our customer’s use cases. We also outline how we went about discovering the root of the issue, how we fixed it, and how we enjoyed solving a complex problem that helped keep the Heroku customer experience as simple and straightforward as possible!
Heroku has been leveraging AWS and EC2 since the very early …

Since April 2021, the Heroku Runtime team has been working to deploy upgrades to the infrastructure powering Common Runtime apps, and we’re excited to formally announce the performance improvements that customers are already seeing.
When this Changelog post was published in May introducing the changes, almost all Common Runtime apps had been migrated from what we internally called the “classic“ infrastructure to the new “sharded” architecture. In addition to performance enhancements, this migration is expected to result in lower latency across the platform.
Around 99.9% of customers didn’t have to make any changes to their Heroku apps to benefit from …

We are excited to announce that we are moving Connection Pooling for Heroku Postgres into GA. Connection Pooling unlocks the ability to use up to 10,000 client connections to a Heroku Postgres Database, without adversely impacting performance on the database. This will unlock more complex and higher scale applications with simpler architectures on the Heroku Platform.
Over the years, one of the factors that you have to consider when scaling applications is pressure on the database. Each connection to the database consumes resources that could be spent on processing requests. The balancing of resources spent on connections and processing is …

Incidents are inevitable. Any platform, large or small will have them. While resiliency work will definitely be an important factor in reducing the number of incidents, hoping to remove all of them (and therefore reach 100% uptime) is not an achievable goal.
We should, however, learn as much as we can from incidents, so we can avoid repeating them.
In this post, we will look at one of those incidents, #2105, see how it happened (spoiler: I messed up), and what we’re doing to avoid it from happening again (spoiler: I’m not fired).

Your app is slow. It does not spark joy. This post will use memory allocation profiling tools to discover performance hotspots, even when they're coming from inside a library. We will use this technique with a real-world application to identify a piece of optimizable code in Active Record that ultimately leads to a patch with a substantial impact on page speed.
In addition to the talk, I've gone back and written a full technical recap of each section to revisit it any time you want without going through the video.
I make heavy use of theatrics here, including a Japanese …
