Adam4EVE    ESI uptime and response time   v0.0.17
ESI available TQ: 31274
ESI (esi.evetech.net) is an API from CCP that provides 3rd party developers like myself and this site with information from within the EVE Online game. Without a functioning API the site will still function, since the data is stored in a local database for historical analysis. However no new data will be added and thus the analysis and information displayed will more and more be out of date.
The previous API called CREST was heavily used by A4E, but was shutdown by CCP on 8th of May 2018 in favor of ESI.

You can see in the top right the status of ESI from A4E perspective and if fresh data is available.

More information and links on ESI can be found here: https://docs.esi.evetech.net/
