A Knology upgrade to internal systems disrupted some @sunflower.com email accounts, said Rod Kutemeier, Knology general manager.

The Monday morning maintenance to the system affected an estimated “5 to 10 percent” of @sunflower.com email users, Kutemeier said. However, no emails were lost during the disruption, and all accounts should be back to normal now, Kutemeier said Wednesday morning.

In addition, other internal router maintenance affected Knology internet connectivity last weekend. Kutemeier said most of the internet connection issues could be solved by customers resetting their routers by unplugging and re-plugging connection cords.

Customers still experiencing problems should call 841-2100 for technical support.
