Even the 3BB website was offline, as for a time, was its 1530 call centre number.
The issued seemed to affect anyone trying to access the sites from a Thai IP address.
3BB customers using a VPN were still able to access the sites without problems.
Customers reported problems from locations including Pattaya, Udon Thani, Phuket, Hua Hin and Chiang Mai.
“Glad I saw your thread. I am in Chiang Mai using 3BB. Been having problems with Google services all morning, very hit and miss. Seems there is a gum up in the works somewhere”, wrote one Thaivisa member.
“Phuket down on 3bb. Vpn works fine,” wrote another.
As well as on Thaivisa, Thai forums such as Pantip.com were flooded with messages from customers experiencing problems with service.
Earlier in the day 3BB posted on Pantip to confirm there was an issue with accessing Google owned sites.
However, at around 11pm on Saturday evening, customers started to report that the issue appeared to be resolved and they could access YouTube, Gmail and other Google services once more.
It is unclear what caused the issue.
