While I was reading the krebsonsecurity.com article cited below, the site, hosted at Akamai address 72.52.7.144, became non responsive and now appears to be offline. Traceroutes stop before the Akamai-SWIPed border within Telia, as if blackholed (but adjacent IPs pass through to Akamai):

Weird coincidence?
