A lightning strike on an overhead power line in France affected local electricity supplies momentarily in Guernsey earlier.
A 90,000-volt cable in northern France which forms part of the Channel Island Electricity Grid supply network suffered a direct strike at 1326 BST.
Automatic protection systems switched the affected power line out of service.
As a result, some islanders saw a momentary flicker on their home or office lighting.
The affected power line was automatically switched back on a few seconds after the strike.
'Several storms'
Cable & Wireless are advising any customers who are experiencing problems connecting to the internet to reset their broadband router.
Guernsey Electricity's Bob Beebe said such incidents were commonplace on large interconnected power networks.
"We have experienced several lightning storms in the last few days on the French peninsula, which are common this time of year.
"The correct protection systems operated seamlessly and restored the high voltage circuit within five seconds. "We have a resilient electricity supply to the islands along with our on island generation capability and no supplies were lost to the islands during the incident."
