UK's VoIP Unlimited hit by DDoSes again, weeks after ransom-linked attacks KO'd it

A British VoIP firm has staggered back to its feet after being smacked with a series of apparent DDoSes a month after suffering a series of sustained attacks it said were delivered by the REvil ransomware gang. In an update at 11:56 UK time, it said it was "continuing to suffer from large scale DDoS attacks. VoIP Unlimited …

viral marketing is going too far

REvil ransomware gang? How far will these advertisers go to hype up new games and tv shows? what next a real zombie outbreak?

Broadband sells VoIP services to a lot of US and Canadian based VoIP providers like voip.ms and CallCentric.

I find it odd to see nothing from El Reg about this attack on this provider.

Interesting. I wonder how many other VoIP providers are currently under attack, and if there is a special motive for it, perhaps an experiment by somebody to see how feasible it is to disrupt phone communications on command.

If it works, it could be a useful weapon when WWIII breaks out...

(fortunately it seems it's not particularly effective.. although it might be a bit more so when BT switches off its landline network in favour of VoIP)

VoIP Unlimited was struggling all last week. I thought they had mitigated by the weekend and it seemed okay this morning (18/10/2021)

However it has started again a couple of hours ago. One-way audio on SIP trunks and a large number of sites blocked from web traffic.

I do feel for the support engineers, who must be suffering hell. However you would think they might be able to block all non-UK traffic to cut down on a lot of the DDoS. The majority of their affected customers must be UK-based.
