cpanel53/cpanel54 servers affected by DDoS

Wednesday, January 4th, 2012

04/01/2012 Wednesday
11:45
The cpanel53 and cpanel54 servers are currently receiving an inbound DDOS (Distributed Denial of Service) attack which can affect network speed and latency, which means some sites may load slower than normal or time out.

12:20 We’re working to block this attack. We have blacklisted a large number of offending IP addresses (mostly in Poland and China) and we are continuing to monitor the network traffic to ensure that we are blocking them all. Unfortunately access to the servers currently remains intermittent and slow.

13:20 This attack is on-going. At this time customers should be able to access their website/email but service may still be slow and intermittent.

15:00 Unfortunately this problem is on-going. Both servers are running a lot slower than we would like and we’re working to block the attack and stabilise the servers. The attack is still large and the offending IP addresses are constantly changing which makes it difficult to mitigate.

16:00 The DDoS attack is still on-going but it has significantly decreased in the last 20 minutes (we’re blocking a very large number of offending IP addresses). Services on both cpanel53 and cpanel54 are beginning to stabilise. We have temporarily disabled the MySQL servers while other services (HTTP and email) are brought back online and stabilised. This will mean websites using MySQL will remain inaccessible (displaying a database error message) but we hope to enable MySQL access again shortly. There is a large backlog of email and all other services are extremely busy after being intermittently unavailable during the attack, and our priority is to keep the servers stable. At an appropriate time we will enable MySQL access and post an update here.

16:40 We have re-enabled MySQL access on cpanel54 server. We are monitoring the server closely.

17:20 We are enabling access to MySQL on cpanel53 server. Please note it will be slow for a while because of high demand.

17:30 We believe this issue is now resolved and we will continue to monitor the servers closely. We are very sorry for any disruption this has caused.

Problem with connectivity in Dublin Clonslaugh datacentre

We are aware of a connectivity problem in our Dublin Clonslaugh datacenter that is currently affecting customers on our shared hosting and virtual servers. We are awaiting more information from datacenter engineers.

13:50 We have been advised that a power board has failed in the Cable & Wireless (Dublin Clonslaugh) datacentre. Technicians are working to resolve this problem. The vast majority of our systems have automatically switched to failover power B circuits however two systems have not automatically switched. This is affecting the switch/router connecting the cpanel1 shared hosting server and a small number of VPS customers.

14:05 Clarification – It’s not just a problem with a switch/router. One of the power boards at the datacentre has failed. We’ve updated our last post to provide the correct information.

14:30 This problem is on-going. Please be assured that the datacentre technicians are working to resolve it urgently. Thank you for your patience.

15:08 Connectivity is now restored. All services are back online and should be back to full speed within a few moments. We apologise for any inconvenience this downtime has caused. Thank you for your patience.

Problem with connectivity in Dublin Clonslaugh datacenter

We are aware of a connectivity problem in our Dublin Clonslaugh datacenter that is currently affecting customers on our shared hosting servers. We are awaiting more information from datacenter engineers.

18:04 A large spike in network traffic caused latency across our Dublin servers and resulted in 10-15% packet loss which was picked up by our network monitoring. This was causing some sites toload slower than normal or time out. The problem should be resolved within a few minutes.

18:10 We believe this problem is now resolved.

Problem with connectivity provider in Dublin Clonslaugh datacenter

We are aware of a connectivity problem in our Dublin Clonslaugh datacenter that is currently affecting customers on our shared hosting servers. We are awaiting more information from datacenter engineers.

20:42 Our datacenter has informed us that they are currently receiving an inbound DDOS (Distributed Denial of Service) attack which can affect network speed and latency, which means some sites may load slower than normal or time out. Our datacenter technicians are working to mitigate this attack.

21:35 This attack is on-going. Our technicians are working to block all the offending traffic from our network however this is difficult because the source of the attack is constantly changing.

23:40 This attack is still on-going however we believe we have blocked the vast majority of the offending traffic. We are continuing to monitor all traffic across our network. Connection speed and latency has returned to near-normal levels. There is still some intermittent packet loss however websites should be back online and working. We are very sorry for any inconvenience this attack has caused. If your website is unreachable please contact our technical support and they will investigate it for you.

00:10pm We believe this problem is now resolved.

11:15 There is a problem with one of the hard drive partitions. Our technicians are working to resolve this problem.

11:25 The hard disk drive is forcing a fsck disk integrity check. We are currently working on this.

11:50 The disk integrity check is still in progress.

12:40 The disk integrity check is still in progress. It is currently on ‘Pass 2′. There are 6 passes to complete in a disk integrity check. The first check always takes the longest and the subsequent 5 checks are shorter.

13:45 The disk integrity check has finished. The server is now rebooting and we will verify that services are coming back online.

13:49 All services are now back online. We apologise for any inconvenience that this disruption has caused.
