I am upgrading my blog to new server and also upgrading from PHP4 to PHP5. I have upped the monthly bandwidth so as to accommodate the latest surge in traffic.
There may be some problem in accessing posts during this time. Please bear with me till that gets resolved. Otherwise I hope the upgrade will be quite painless and should be over within days.
Edit: Now my blog is upgraded to PHP5 & a brand new server with huge bandwidth succesfully. If you find any problem please let me know.
