It's not an SMF issue - that's our forum software - but a server issue (OLI). I contacted customer support at OLI and they responded within minutes. We've been emailing back and forth for the last 30 minutes or so. Here's the latest:
We pinpointed the site on the server that was under attack and causing the high traffic, and are working on a solution now so the server should go back to normal.
TX - USA
DS - peanut, tree nut, milk, eggs, corn, soy, several meds, many environmentals. Finally back on Xolair!
DD - mystery anaphylaxis, shellfish.
DH - banana/avocado, aspirin. Asthma.
Me - peanut, tree nut, shellfish, banana/avocado/latex, some meds.
