Availability issues

It seems our website is having some availability issues, see the email I received from an ISP. As a sidenote, is there a support email (or at least a supoprt form) that I could refer the ISP to, so that they don't have to go through the tedious process of forum registration just so they can resolve a technical issue? I tried, but wasn't able to find it.

I'm also told that it's not just our club's website but also other clubs' websites as well as the toastmastersclubs.org website. The issue still persists.

Those IP were blocked because of a hack attempt.
I have removed the block for now.

Thank you for prompt action! In case you would like to share details of that hack attempt (I think the ISP would appreciate it), the contact is:  jiri.hudecek@ecomp.eu .. Hopefully it doesn't happen again.

Take care,
Ondra

No we just block the ISP the attacks come from they happen so frequently.
