(Reuters) - Twitter said on Tuesday outages affecting the social network on computers and phones, widely reported across Europe, the Middle East, Africa and North America, were caused by a glitch in a software update and had been resolved.

In a status update at 1800 GMT Twitter said what it described as an "intermittent issue affecting some users" was related to what it called "an internal code change."
