I’m not entirely sure of the exact time, but based on the trend chart of the upstream AS monitoring data I retrieved from the Looking Glass API, it should have started between 9 AM and 10 AM (UTC) on June 16, 2026. The API call didn’t time out and returned an HTTP 200 response, but no valid data was returned.

This is a program I developed myself to periodically retrieve Looking Glass information with a specific prefix and visualize the data. I retrieve Looking Glass information with a specific prefix every minute.

As you can roughly see from my chart, my data was very complete up to 9:00-10:00 (UTC) on June 16, 2026.

I can only upload one image. I’ve monitored a few prefixes, and this is the case for most of them.

The request results are similar to the following — the HTTP response returns a 200 status code, but there is actually no content in the response body. Taking 8.8.8.0/24 as an example, this is the prefix where a well-known DNS server is located:

I requested the following URL: [https://stat.ripe.net/data/looking-glass/data.json?resource=8.8.8.0/24](https://stat.ripe.net/data/looking-glass/data.json?resource=8.8.8.0/24)

Although the server returned data, there is a chance that the data content is empty. Below are the request results for a well-known DNS prefix:
