For a better understanding of the indicators, see calculate visibility
The graph shows the visibility of a network (as described in chilean networks visibility) calculated every 5 minutes between days 25/02/2010 to 02/03/2010
The graph shows the number of paths from a RIPE RIS collectorto the network between 25/02/2010 to 02/03/2010.
Disclaimer: Visibility indicator plots the network status to block IP Chilean entered. Visibility indicator shows the changes of visibility in time for that block of IP addresses. It is normal visibility and advertising numbers are not 100% for large blocks, what matters is that the day of the earthquake should be equal to the previous days. Generally, also note that the following days to 27 the numbers are a little lower than normal. If you enter a domain name search, the current IP may not correspond to the ip of the day the earthquake.
