I have an offer for 100 Mbit/s network speed in as a co-location service.
100mbit includes download/upload all together?
For example: Can I upload with 100Mbit/s while downloading 100Mbit/s at same time?
This question appears to be off-topic. The users who voted to close gave this specific reason:
Yes, this should be full-duplex bandwidth... But check the terms of the offer to make sure that language is there.
Make sure you understand the billing metrics. For instance, unmetered and burstable/95th percentile are vastly different and need to be planned for...
