Twitter crashes caused by software bug, disturb NBA-related ad campaign

<i>This post has been corrected. See note below.</i>

Twitter says its intermittent outages Thursday have been caused by a software bug.

The microblogging service has been crashing frequently throughout the day as a result of a “cascaded bug,” which is a glitch “that isn’t confined to a particular software element,” a spokesman for the company said.

“Its effect ‘cascades’ into other elements as well,” he said.

At one point, I was unable to access the site for more than half an hour, and throughout the day it seemed to be running slower than normal.


Twitter said it would provide updated information about the crashes soon. For now, Twitter’s status website continues to say that the issue is ongoing and that the company’s engineers are trying to solve it.

The company did not provide information about how widespread the crashes were, how long they lasted or how they have affected its advertisers.

It also was unclear how the crashes affected Kia Motors’ ad campaign, which Thursday was promoting the trend "#NBAFinals” leading up to Thursday night’s NBA Finals Game 5 between the Miami Heat and the Oklahoma City Thunder. Twitter did not respond to questions about how its crashes affected Kia Motors’ paid campaign.

[For the record, June 21, 3:15 p.m.: An earlier version of this post said the "#NBAfinals” ad campaign was by the NBA. It was actually by Kia Motors America.]
