Some on-demand services on the Internet experienced delays or failures Saturday.
Outages with online services such as GitHub, Pinterest and Tumblr affected some users for more than a half-hour. Service is now recovering.
Kevin Mandia, founder and CEO of WhiteHat Security, tweeted on Saturday that the issues were with Cloudflare, a company that provides an internet backbone of encryption. Cloudflare services 250,000 clients.
The service was scheduled to expire at 10:59 p.m. ET on Saturday, but has been temporarily available until Monday at 8:59 p.m.
Cloudflare confirmed that services were unavailable for several minutes Saturday evening. “We are back up and running,” the company said in a statement. “At this time, the source of the issue does not appear to be Cloudflare.”
GitHub, the programming service popular among developers, said in a message on Twitter that it was working with Cloudflare on resolving the issue.

WordPress announced in an email update that some of its users experienced connectivity issues Saturday.
“We believe that the root cause of the issue is internal CDN-related. We are currently re-architecting our CDN infrastructure,” the message said.
Blogger Confirmed said its on-demand blogging platform, Blogger, is also not available.
The outage does not appear to be related to Saturday’s threatening ransomware message that circulated online.
