Hi,
You are providing Slack notifications. It would great to get Matrix notification (matrix.org). Open source. Open API.
Thanks.

Whitelabled emails!

Weekly reports, restricted to which sites they are associated with, sent to alert addresses with or instead of the one sent to the account email address

Add phone number to SMS to exclude from Do not Disturb mode. During the night my iPhone is within "DND" mode and the updown.io service does not send a phone number. I am not able to exclude the messages from the DND mode because I need to create a contact for this which is not possible because there is no phone number

Having the ability to set an "alias" for each SMS number would be very helpful.

For example, I would like to add a label for SMS +1 5551234567 that reads "Marc's mobile", that way I can easily see who will receive which notifications.

Easier description/show : of load time compared to expected load time

It would be great to have the option to add secure the public status page with a password. Could be as simple as a htpasswd.

It would be great if you could sent custom headers (and values) in webhook requests. This would allow you to add an API-key as a header which you can check in the system receiving the webhooks to validate it is actually the updown-io services sending the request.

Currently this is do-able by adding a GET-parameter with a key to the webhook URL, but sending custom headers would be a more preferable option.

Let people subscribe to my status page via email

It is already possible to "Be alerted (by email) when your website's Apdex drops more than 0.3 in 1 hour". It would be great if this event could also send a webhook-request. This would allow us to be automatically notified in our custom monitoring-system when the Apdex suddenly drops for a website.

Geckboard is a popular system to display a variety of metrics via a dashboard for the room. I understand this can probably be done with the API, but if you did a direct integration with them I'm sure you'd see your sign-ups increase since you'd be on their integration list.

Just my 2 cents worth. :)

We have a couple of long running dashboard pages and a higher timeout threshold would be useful

Apdex alerts are currently hard-coded to 0.3 in 1 hour. It'd be nice if we could set the the threshold to a custom value rather than hard-coded at 0.3

More specifically, we display the status page on a widescreen TV, and we have to zoom out to fit the height of the status page, leaving a lot of unused space on the sides.

Alert via automated voice call to multiple numbers

There is a credits usage estimation based on the current load. However our credits are mostly used by SMS messages. The current estimation is usefull but it would be great to also have an estimation based on past usage (inclunding SMS messages).

mtr details for failed icmp

When I'm logged in, I can view our status pages at updown.io/[token]

But we do monitoring for clients, and it would be great if we could share an URL to a private status page like updown.io/[token]?[random_passkey] which would allow people who have that URL to view the status page, even if they are not logged in.

The random passkey would be an automatically generated alphanumerical string. There would have to be an option to expire a passkey and have a new one generated.

Would love an option in the dashboard to sort checks by apdex, to make it easier to see which of our sites are not doing so well.
