A minor update has been running on https://api.testeveonline.com for some time, see here.

The plan is to deploy this to TQ tomorrow Wednesday at around 10:00 GMT. There should only be a few second downtime of the API while we switch over to the new version.

The changes are mostly internal:

  • Removed uneccessary IIS and .net related HTTP headers
  • Removed the cache-control header (now that we are on https only there is no way to cache responses on proxies anyway)
    • - This was causing issues for some VBA code in Excel
    - If anyone is using or providing a HTTPS->HTTP proxy service for the API you need to be aware of this as it will allow non-HTTPS proxies to start caching your private information. If you stay on HTTPS it is not an issue.
  • Replaced the underlying distributed cache service (shouldn't affect anything but please report to this thread if you notice anything weird)
  • Preparing for enabling gzip for XML endpoints
    • - I will start introducing gzip to the XML endpoints while closely monitoring what effect it has on the API server machines the day after deployment.

Thanks for letting us know. My software usually hangs if it encounters any API downtime because it's so badly written, so at least now I can restart it before the angry EVE mails arrive (they always do).

This was done at 10:00 this morning. Forgot to notify this thread, sorry.

Worked fine for several hours (so I'm glad it's not related to the switch), but now API calls seem to be failing:

I'm experiencing the same latency. Responses delays, often result to request timeouts. Wasn't sure if it was on my end though.

Is there any new API calls coming, ie - CREST? I keep seeing rumors on unofficial pages but yet to find anything official. Maybe I'm not looking in the right place?

Something I have needed recently is a call for corp bookmarks, ie. What systems we have them in. Any chance of this in the future?

Yes we already have spies in your corp muwhahahaha

Wasn't your script, was the API servers.
Even saw them crash today, CCP already informed (big thumbs up for PrismX being on IRC and notifying Ops for us!).

Not sure if it's fixed yet, but I've disabled my API calls for now.

Performance has hopefully stabilized but we are not entirely out of the woods yet. We believe this to be an issue with our distributed cache solution introduced in yesterday's deployment and have reverted to the previous version of the API on some of the machines in the cluster while we figure this out.
I will keep this thread updated on our progress.

Probably you are trying your distributed cache solution again, cause timeouts returned.

Update: Seems that they have stopped now.

The API has been fully reverted to its previous state. The distributed cache configuration just couldn't handle the load and we will need to take this experience to the lab and figure out our next move.

    Does this mean GZIP is put on the backburner ? Cry

    Until we figure this out then yes. This week will be quite busy deploying Retribution but I plan to revisit this as soon as possible. Just can't promise a set time as I need backup from more people to finish this.
