I stared at data about the Internet for Cloudflare. (on hiatus)
The #earthquake in #Colombia had a nominal impact on #Internet connectivity, per @radar.cloudflare.com data. Traffic dropped 35% compared to the prior week. Traffic at an ASN level appeared to recover quickly. Some loss of announced IP space, suggesting infrastructure damage as well.

The electric grid in #Cuba has collapsed for the 3rd time this month, causing a widespread power outage. @radar.cloudflare.com shows traffic falling around 15:00 UTC (15:00 local), and @ioda.live shows active probing failures around that time as well. en.cibercuba.com/noticias/202...
The impact of the latest island-wide power outage in Cuba is visible in @radar.cloudflare.com traffic data, as well as @ioda.live active probing data, with drops visible around 16:00 UTC. radar.cloudflare.com/traffic/cu?d... ioda.inetintel.cc.gatech.edu/country/CU
He would regularly cover the Akamai State of the Internet report back when I was writing it. Had the opportunity to meet him at a GigaOm event, and got him to sign my copy of Broadbandits. A big loss for the industry.
Data from @radar.cloudflare.com shows a [complete loss of announced IPv4 & v6 space](radar.cloudflare.com/routing/lc?d... ) from Flow St. Lucia starting at 21:00 UTC, and with it, a complete loss of traffic from the network, impacting connectivity island-wide. stlucianewsnow.net/flow-reports...
A widespread power outage in #Jamaica is impacting #Internet traffic from the island. @CloudflareRadar shows traffic fell ~0200 UTC, with the largest impact to FLOW Jamaica. The provider acknowledged the issue in a Facebook post. radar.cloudflare.com/traffic/jm?d... www.facebook.com/FlowJamaica/...

Thirty years ago, I published my Bachelor's thesis, The Network Nation Revisited, a critical review of predictions made in 1978 about the future of Computer Mediated Communication. 1994 may have been a bit too early, but much has changed in 30 years... thesis.dbelson.com
