Two UK VoIP operators have had their services disrupted over the last couple of days by ongoing, aggressive DDoS attacks.
South Coast-based Voip Unlimited has confirmed it has been slapped with a “colossal ransom demand” after being hit by a sustained and large-scale DDoS attack it believes originated from the Russian cybercriminal gang REvil.
This morning, it confirmed that “services are operational … however the attacks are still ongoing.”
Separately, London-based Voipfone (see status page here) said it is still suffering outages on voice, inbound and outbound calls, and SMS services.
