TalkTalk Business customers were forced to survive without email nearly a week after a technical fault disrupted domain hosting. Problems began on the evening of Wednesday, April 9, when a mystery glitch affected the domain hosting and left some users without email. According to one customer, TalkTalk “admitted they have made a mistake in changing the settings for a number of Domains that they host.” Another user told El Reg: "We had clients’ name servers changed and they lost email. We contacted TalkTalk who took 24 hours to respond; they said it [is] not malicious and is a global outage. “TalkTalk then go on to say that this is a technical fault on their end, and they are aware and working on the issue.” The problem looks to be a classic DNS disaster, where DNS records are edited and no longer point to the right place. A reader told us that name servers had been changed to Cloudflare with no configured DNS records and no ability for users to change those records themselves. … Despite its size, the telco was unable to provide The Register with a statement explaining what had happened and why some customers found their email connectivity suddenly cut and websites offline. …
….soooo was there an SLA on this… and how much in penalties will this cost? Asking for a friend…
