Denial of service on core web servers

Thursday, May 22nd, 2008

We had a Denial of Service attack on all our core hosting servers starting at 3:30 this morning and lasting approximately 3 hours.

No server errors were reported but website access may have been slow/timing out. We have blocked the source of the attack from accessing the servers and notified the responsible service providers.

For more information please contact support@userve.net

Inbound Email Problems

Monday, May 5th, 2008

We are currently experiencing a delay on inbound email due to high load on our antivirus system.

No email will be lost customers with antivirus scanning may find  that their email is delayed this morning. We expect the problem to be resolved within the next few hours.

Please email support@userve.net for more information.

Web Server Email Changes

Monday, May 5th, 2008

We have recently had large problems with spammers using security holes in customer websites to send out unsolicited email.

Most sites with email functionality are configured by default to use the web server itself as the reply address. This makes tracing the source of the emails near impossible. We have therefore had to take the step of disallowing any mail that doesn’t have a valid reply address.

If you have a website hosted with us that has a legitimate reason to send email, please ensure that your site is configured to provide a valid, working reply address or you may find the emails are no longer delivered.

These steps should ensure that our services remain stable and responsive for our customers.

If you have any problems or need help checking your site, please contact support@userve.net.

Internet Routing Problems

Friday, May 2nd, 2008

There currently seems to be some routing issues at the main london internet exchange which may affect customers entering our network via that route.

These problems will affect a large number of ISPs and you may notice intermittent problems browsing the internet.

The problem is curently being monitored and seems to be slowly stabalizing.
