The number of Snowflake users declined in February, for reasons that are not fully understood.
The apparent one-day dip at 2023-02-16 is not a real reduction in users, but a metrics collection error. A restart of the snowflake-01 bridge for a security update, marked with a vertical line, resulted in the loss of part of the previous day's metrics.

Part of the reason is that the default rendezvous method, based on domain fronting, continued to be sporadically blocked in some networks in Iran. An OONI chart shows the days when the rendezvous domain had more than zero anomalies:

The greatest decline per country was indeed in Iran, which lost about a third of users in February, going from 60,000 to 40,000.
