Thousands of people across the world were denied access to websites as Google services went down yesterday.
Many internet users experienced slow services and were unable to access Google and other websites.
Google said that due to an error it had to redirect traffic through Asia, which caused a traffic jam.
"As a result, about 14% of our users experienced slow services or even interruptions. We have been working hard to make our services ultrafast and 'always on', so it is especially embarrassing when a glitch like this happens," said Google.
"We are very sorry that it happened, and you can be sure that we will be working even harder to make sure that a similar problem won't happen again. All planes are back on schedule now."
The downtime serves as a warning to businesses about their reliance on the internet.
US think-tank Nemertes warned last month that unless the network infrastructure of the internet is upgraded, users will experience slower and unreliable connections by next year.
Nemertes said as demand for bandwidth potentially doubles, computers will regularly start freezing and dropping offline as early as next year.
