San Marino experienced a connectivity disruption affecting its internet routing control plane on Friday. The event began at 10:50 UTC and lasted approximately 1.7 hours, concluding by 12:30 UTC. The primary technical impact was a reduction in the visibility of the country’s Border Gateway Protocol (BGP) routes.
Technical Details
The disruption recorded a severity score of 243. The affected bgp.median signal, which measures the control plane visibility of a country’s advertised IP prefixes, showed a 2% drop from its peak. The median number of visible BGP routes for San Marino fell from a peak of 165 to a low of 161 during the event. Other network signals, including active probing for reachability and traffic backscatter measurements, showed minor fluctuations but no significant correlated outages.
Reported Cause
The cause has not been publicly attributed.
Connectivity was reported restored by the end of the observation period.
