The ship of ThESIus

Greetings, developers. Replacing RabbitMQ with… RabbitMQ? As we briefly touched upon in the EVE Evolved dev blog, one of our goals is to get ESI better connected to the Quasar ecosystem. Currently, ESI connects to the monolith via two distinct channels; sending Quasar protobuf messages, and sending ‘old’ JSON requests. Both of these go over...

ESI Incident Report - 26 Feb 2025

Yesterday just after downtime about 50% of the ESI endpoints did not return to their normal state. This incident was caused by a misconfiguration in the RabbitMQ broker that sits between ESI and the Monolith, and prevented the Monolith from receiving (and responding to) requests from ESI. This caused ESI requests to stall and error out after their configured timeout of 10 seconds. ESI requests that were routed through Quasar were not affected by this issue.

And once again, welcome to developers.eveonline.com

Engineering Capsuleers. A little over 10 years ago we introduced the first iteration of the developer portal. This enabled the creation of third party applications through the EVE SSO, giving developers access to characters' data through CREST and the XML API, and later, ESI. As part of this year's plan to strengthen ESI and its infrastructure, we've set out to create a new and improved developer portal, and today, I would like to introduce you to it.
