What is DNSimple?

DNSimple's origin name servers answer a quarter faster at p90 after erldns work

DNSimple keeps tuning the Erlang stack it now runs end to end. The November 4 post says p90 query time on its origin name servers is down about a quarter, and about a third for DNSSEC queries, with roughly a third less CPU, and record changes now switch in one step so existing records never briefly disappear. It follows October's dns_erlang rewrite, which cut CPU per query by 12%, and the August finish of the migration to fully owned infrastructure. Above that layer sit the CLI launched in May, browser login from June, and Domain Trustee.

What is Ably?

Ably's AI Transport hits 1.0 and plugs straight into Vercel's useChat with resumable streams.

Ably is repositioning its realtime pub/sub network as the transport layer for AI agent output. AI Transport JS 1.0 runs on ordinary Pub/Sub channels and ships adaptors for the Vercel AI SDK, OpenAI Responses API and AG-UI, plus a useChat transport that resumes a stream after a reload. It lands a week after the switch to monthly-active-user pricing and breaking SDK majors that split every client into device and server packages.

DNSimple's origin name servers answer a quarter faster at p90 after erldns work

◆ Current state

DNSimple keeps tuning the Erlang stack it now runs end to end. The November 4 post says p90 query time on its origin name servers is down about a quarter, and about a third for DNSSEC queries, with roughly a third less CPU, and record changes now switch in one step so existing records never briefly disappear. It follows October's dns_erlang rewrite, which cut CPU per query by 12%, and the August finish of the migration to fully owned infrastructure. Above that layer sit the CLI launched in May, browser login from June, and Domain Trustee.

◆ Where it's heading

Since owning its full DNS edge, DNSimple has turned to measurable performance work on erldns and dns_erlang, published openly. The product layer above, CLI and API clients, is moving more slowly.

◆ Prediction

Expect more erldns and dns_erlang performance posts; the entries show no sign of a new customer-facing product soon.

Ably's AI Transport hits 1.0 and plugs straight into Vercel's useChat with resumable streams.

◆ Current state

Ably is repositioning its realtime pub/sub network as the transport layer for AI agent output. AI Transport JS 1.0 runs on ordinary Pub/Sub channels and ships adaptors for the Vercel AI SDK, OpenAI Responses API and AG-UI, plus a useChat transport that resumes a stream after a reload. It lands a week after the switch to monthly-active-user pricing and breaking SDK majors that split every client into device and server packages.

◆ Where it's heading

The November releases fit one plan: split clients so MAU billing can count end users, then make the AI layer a thin adaptor on top of the same channels used for chat, presence and LiveObjects. Server-side additions in Java and JS (HTTP LiveObjects, channel pools, a Temporal plugin) point at agent backends as the intended publisher.

◆ Prediction

Expect more agent framework adaptors and server SDKs reaching AI Transport parity, with Chat and LiveObjects examples built around agents joining human conversations.
