I couldn't use twitter or github from noon till 4. If they mitigated the third attack and no customers were affected, why were github and twitter still down for me?
Same for us. We're backed by Shopify and it was down until 4pm. Not sure I buy they quashed this by 1pm
Can confirm as well. GitHub was inaccessible until about 5PM, and I'm in the southwest. My provider peers with Level3, so it looks like nearly everything gets routed through Los Angeles.
