AT&T WorldNet crushed by spam e-mails

AT&T WorldNet's e-mail slowed to a crawl Monday after the service provider's network was attacked by a deluge of spam.

AT&T Corp.'s e-mail servers, which primarily support consumer e-mail accounts, were bombarded by unsolicited e-mail bombs from "several different domain name" servers, according to an AT&T spokeswoman.

Once AT&T identified the source of the spam it blocked those domain names from accessing its network, thereby shutting down the attack. But the spam attack created a backlog of e-mail, which AT&T is still trying to deliver at this time. AT&T expects to have all of its e-mail queues cleared out by the end of Tuesday, she says.

The problem spread across AT&T WorldNet's entire network with some subscribers noticing more delays than others. AT&T WorldNet customers were able to send and receive e-mail from other WorldNet customers without a problem. But downloading e-mail from users on other ISP networks became a problem for many.

AT&T is still investigating the attack and says it intends to find out what happened and what the attackers were trying to accomplish. A root cause analysis will take four to five days.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
