Interesting timing as Vodafone had a complete (AFAICT) failure of ALL their leased lines and FTTC connections yesterday - but more importantly, it took our mobile data as well.
Seems they route all the leased lines through one point of failure and it lost power. Then when they switched it all back on again, only some of it started up. Some of us lucky ones were back online in 10 minutes - some of our customers didn't get back online until 11pm and I believe there were some not online until getting on for 4am !
Curious that I've found barely any mention of this online so far - perhaps "business users" losing internet aren't newsworthy enough to mention.
Anon as I don't want b***ocking for posting this from work.
