Google services are getting frozen


we are facing intermittent issue in accessing google services.
Anything which is searched on chrome is getting frozen(gives just a blank page). the page needs to be refreshed twice or thrice to load the page correctly.
This is happening only on for google sites. Other sites are accessible without any issues.

Upon checking wireshark logs we found only DNS requests but not connect or get requests to the page accessed.

since last week we have this issue. anyone else is facing similar issue??
