IPNI Uptime per Day

IPNI Uptime per Day

This graph shows the uptime of the InterPlanetary Network Indexer (IPNI) cid.contact.

The legend means the following:

  • Up The IPNI accepted our advertisement announcement and indexed the content within 5 minutes.
  • Delayed Ingest The IPNI accepted our advertisement announcement but a later step timed out, for example the content was not indexed within 5 minutes.
  • Down Another error happened while we published the content, for example the HTTP call to the /announce endpoint failed.
  • Unknown We don't have valid data for this time period. Measurements in which the IPNI answered 429 Too Many Requests count as measurement errors, so their time also shows as Unknown.

Our Parsec measurement nodes in several regions regularly publish content to the IPNI. When we detect a state, we consider the IPNI to be in that state until the next measurement from the same region, but at most for 15 minutes or for 5 minutes (the index timeout) times the number of regions, whichever is longer. If the next measurement comes later, the time in between shows as Unknown. Each bar shows the share of the day in each state, averaged over all regions. The tooltip shows the number of measurements (samples) of the day.

Before the dashed Changed Calculation line (late October 2025), the chart shows a simpler calculation: the share of our published CIDs with an error (Down) and without an error (Up). This could have incurred biases and we consider the new calculation to be more accurate.
