Our technical team are aware of the issue and are working on it
We will update with more information as soon as we have it
UPDATE 2300 - the issue appears to be a DDOS against our DNS servers which is affecting any service that uses them.
UPDATE 0005 - Our network engineers are working on the issue. Due to the nature of the attack it is impacting sites and services on our shared network ie. more than DNS.
UPDATE 0017 - our main site, control panel and most client sites *should* be accessible now. We're confirming any outstanding issues
UPDATE 1135 - The network issue was fully resolved last night. One or two clients reported issues this morning that were unrelated.
With respect to the issues last night I am still waiting on a more detailed explanation from our technical team, but in simple terms what happened was as follows
Something / someone launched a large attack against us sending a very large amount of DNS queries / packets of data. The huge spike in queries basically maxed out the firewalls that protect that segment of our shared hosting network.
Once our technical team were able to identify the network block that was being hit they were able to take actions to remedy the situation.
All shared hosting services were functional again from around midnight last night. We are aware of one Windows webserver that had an issue last night, but it is, as far as I know, unrelated.
If we can get a more detailed explanation of last night's issue we'll post it here / edit the post
