It's plauseable, but doubtful... I mean, without knowing how they do their backups it's hard to say really... It could be process intensive...

Is it just a specific time period, from X and Y hour that you see slowdowns, and does it get faster after Y?

I am looking to shift to a new host and I have been recommended GODADDY which is US based. Does anyone know if they are a good host as I am really get upset with the host here in OZ (no service or real help).

One vote from me against GoDaddy. I'm sure some people have good and some people have bad experiences with them. They've never hosted for me. The few times I've dealt with them on ohter issues, they lacked knowledge. I think they are for newbies taking their first steps into having their own site.

i use them for ONLY registering my domains.. for that service, i love them..

as for hosting.. dunno..

Heres another vote AGAINST using them as a webhost; they're great for domains, but they should leave hosting to larger companies which own datacenters vs trying to expand their market lol

Not into the "big names" for basic registrar services -- gkg.net for me. (Anything but NetSol, basically). But for hosting, no idea... still searching myself after 13 years! ASO support is A+, but that's about it for shared hosting. :/
