Broadband subscribers in Hull were left disconnected last weekend after a network failure disrupted communications throughout the city.
KCom, a provider which supplies a large portion of Hull with broadband services, experienced the problems which affected its Karoo and Kingston Communications from a period of around 15:00 GMT on Saturday, August 9th to 22:00 GMT that night.
According to reports, communications between hospitals were hampered during the outage.
In a statement passed to technology news provider the Register, the firm commented: "We sincerely apologise for any inconvenience this caused our customers who were trying to access the internet during this period. "We are working to understand the exact root cause of the issue and ensure that appropriate actions are taken to mitigate the risk of it happening again."
Many residents in Hull have complained at the broadband monopoly enjoyed by KCom's Kingston Communications, with calls for competition in the area to be opened up being voiced.
