HTTP 403: Maintenance

In some rare cases, the Websolr Ops Team will put a index into maintenance mode. There are a lot of reasons this may happen:

  • Load shedding
  • Data migrations
  • Rolling restarts
  • ... and more.

When this happens, writes to the index will fail with this message:

{"code":403,"message":"Slice is currently read-only for maintenance. Please try your request again in a few minutes. See or contact for updates."}

Maintenance mode blocks updates to the index, but not searches. If you're seeing this message, it will be temporary; it rarely lasts for more than a minute or two. If your index has been in a maintenance state for more than a few minutes, please contact support.
