At approximately 7.30 this morning the Conservative Party website was subjected to a Distributed Denial of Service (DDOS) attack caused by multiple source host machines on the Internet - presumably working as a remotely controlled bot-net. It is currently still running very slowly.
Currently, the Liberal Democrats website is also down, it simply states that the server is timing out at their network gateway, confirmation that they are subject to a DDOS is yet to be established but the timing is interesting.
The Labour Party website appears unaffected, as does UKIPs and the BNPS.
Update: The Lib Dems website is now, occasionally, just about managing to display an "Oops something is wrong" message. Am currently trying to contact Mark Pack but his phone is being very odd.
Update II: (09.44) Have just spoken to Mark Pack who said they are currently investigating what is going on. They have had some hiccups this week so he's not jumping to the conclusion that it is linked as yet, but he noted that it is certainly strangely coincidental.
