An island-wide power outage in #Cuba has impacted #Internet connectivity across the country. Starting around 17:45 UTC, @radar.cloudflare.com data shows traffic dropping by >50% compared to the prior week, and @ioda.live shows a 10% drop in successful active probing.

I’m getting down to the wire on this with three days to go. If you’d like a hardcover book full of enjoyable weirdness and rabbit holes—a great gift for friends and family interested in type, printing, and language—pledge now, as the campaign is not yet at 100%! Thank you.

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.

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.
